WARNING! Read and understand all instructions. Failure to follow all instructions listed

below, may result in electric shock, ﬁre and / or serious personal injury. The term ‘power

tool’ in all of the warnings listed below refers to your mains-operated (corded) power

tool.

SAVE THESE INSTRUCTIONS.

1. Keep your work area clean and well lit. Cluttered worksites and dark areas invite accidents.

2. Do not operate power tools in explosive atmospheres, such as in the presence of ﬂammable liquid,

gases, or dust. Power tools create sparks which may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause

you to lose control.

1. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with

all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do

not use any adaptor plugs. Check with a qualiﬁed electrician if you are in doubt as to whether the

outlet is properly grounded. If the tools should electrically malfunction or break down, grounding

provides a low resistance path to carry electricity away from the user.

2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators.

There is an increased risk of electric shock if your body is grounded.

3. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the

risk of electric shock.

4. Don’t abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep

cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

5. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These

cords are rated for outdoor use and reduce the risk of electric shock.

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not

use tool while tired or under the inﬂuence of drugs, alcohol, or medication. A moment of inattention

while operating power tools may result in serious personal injury.

2. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal

injuries.

3. Avoid accidental starting. Be sure switch is off before plugging in. Plugging in tools that have the

switch on invites accidents.

4. Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left

attached to a rotating part of the tool may result in personal injury.

5. Do not overreach. Keep a proper footing and balance at all times. Proper footing and balance

enables better control of the tool in unexpected situations.

6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

1. Do not force tool. Use the correct tool for your application. The correct tool will do the job better

and safer at the rate for which it is designed.

2. Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

3. Disconnect the plug from the power source before making any adjustments, changing accessories,

or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

4. Store idle tools out of reach of children and do not allow persons unfamiliar with the power tool or

these instructions to operate the power tool. Tools are dangerous in the hands of untrained users.

5. Maintain tools with care. Properly maintained tools are less likely to bind and are easier to control.

6. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that

may affect the tools operation. If damaged, have the tool serviced before using. Many accidents

are caused by poorly maintained tools.

7. Use the power tool, accessories and blades etc., in accordance with these instructions and in the

manner intended for the particular type of power tool, taking into account the working conditions

and the work to be performed. Use of the power tool for operations different from those intended

could result in a hazardous situation.

Have your tool serviced by a qualiﬁed repair person using only identical replacement

parts. This will ensure that the safety of the power tool is maintained.

Tool Use & Care

Service

1. Keep hands away from rotating sanding head area at all times!

2. Prolonged breathing of airborne dust from plasterboard sanding may effect respiratory function

or cause serious respiratory illness. To reduce exposure to dust always wear approved protective

equipment*, ensure Power Sander is connected to a vacuum approved for ﬁne dust extraction and

operate the tool in a well ventilated area.

*Wear Eye Protection to AS/NZS1337.

*Wear Respiratory Protection to AS/NZS1716.

*Wear Hearing Protection to AS/NZS1270

3. Sanding LEAD-BASED paint is extremely toxic and should not be attempted. Only allow

professionals with special training and equipment to perform this task.

4. Maintain proper footing and balance at all times. Do not overreach. Use proper scaffolding

5. Always wear appropriate safety equipment when operating.

6. Important: After completing sanding, switch off the switch and wait for the coasting sanding head

to stop completely before putting the tool down.

7. Never operate the tool in an area with ﬂammable solids, liquids, or gases. Sparks from the

commutator/carbon brushes could cause a ﬁre or explosion.

8. There are certain applications for which this tool was designed. The manufacturer strongly

recommends that this tool NOT be modiﬁed and/or used for any application other than for which

it was designed. If you have any questions relative to its application DO NOT use the tool until you

have written to the manufacturer and have been advised.

9. Use the machine with both hands at all times. Loss of control can cause personal injury.

10. Keep power supply cord clear from the working range of the machine. Always lead the cable away

behind you.

11. Immediately switch off the machine if unusual vibrations or if other malfunctions occur. Check the

machine in order to ﬁnd out the cause.

This Electric Plasterboard Sander is specially designed for the most efﬁcient sanding of plasterboard

or plaster walls and ceilings for both new construction and renovation work. It is designed to work in

conjunction with a vacuum cleaner for minimum dust and best sanding results. The pivoting sanding

head allows excellent results with minimum time and effort.

Electrical connection

The network voltage must conform to the voltage indicated on the tool name plate. Under no

circumstances should the tool be used when the power supply cable is damaged. A damaged cable

must be replaced immediately by an authorized Customer Service Center. Do not try to repair the

damaged cable yourself. The use of damaged power cables can lead to an electric shock.

Extension cable

If an extension cable is required, it must have a sufﬁcient cross-section so as to prevent an excessive

drop in voltage or overheating. An excessive drop in voltage reduces the output and can lead to failure

of the motor. The following table shows you the correct cable diameter as a function of the cable length

for this machine. Use only U.L. and CSA listed extension cables. Never use two extension cables

together. Instead, use one long one.

Unpacking

Carefully remove the tool and all loose items from the shipping container. Retain all packing materials

until after you have inspected and satisfactorily operated the machine.

2. Vacuum cleaner hose

3. Instruction manual

DO NOT OPERATE THIS TOOL UNTIL YOU READ AND UNDERSTAND THE ENTIRE

INSTRUCTION MANUAL

To install a sandpaper disc:

1. Unplug the machine.

2. Peel away the worn out sandpaper disc, leaving the sponge backing pad in place.

3. Carefully center the new sandpaper disc and press into place. It will be held securely by the hook

and loop backing.

To replace the Hook and Loop Sponge Pad:

The sponge pad must be perfectly ﬂat to get good sanding results. If it is deformed or damaged it will

cause very uneven sanding. Always replace it when damaged. It is hook and loop on both sides, so

to replace it, peel it away from the hook and loop on the Sanding Plate Base and, taking great care to

keep it perfectly centered, afﬁx a new one.

The Brush Bristles on the edge of the Sanding Plate Cover:

The brush bristles on the edge of the Sanding Plate Cover serve two

purposes, they keep the sanding disc properly aligned with the work

surface without gouging and they also help the efﬁciency of the dust

collection by the vacuum cleaner. These brush bristles will wear with

continued use.

The Sanding Plate Cover should be replaced when the bristles are too worn

to ensure effective dust collection and stabilization of the sanding head.

To replace, hold the center bolt from turning with a slothead screwdriver

and unscrew the sanding plate. Then, using snap-ring pliers, remove the

circlip which holds the sanding plate cover to the bracket. Remove the

vacuum hose and lift sanding plate cover away.

Replacement is the opposite of removal. Entrust all repairs to an

authorized service center.

NOTE: Only use sandpaper discs which ﬁt properly and which are designed for vacuum use.

Instructions

To install the vacuum cleaner hose:

1. Unplug the machine.

2. Plug the vacuum cleaner hose bayonet mount into the swivel mount

in the back of the machine. Once the tangs of the bayonet mount are

fully inserted in the slots, hold the swivel mount from turning and turn

the hose bayonet mount clockwise to lock.

3. Removal is the opposite of assembly.

The vacuum cleaner:

Ensure that you have a bag installed in your vacuum cleaner which is approved and rated for

plasterboard dust.

WARNING: Failure to use an approved dust bag in your vacuum will increase the level of

airborne dust in the work area. Prolonged exposure to such dust may cause respiratory harm.

Make sure that the power circuit voltage is the same as that shown on the speciﬁcation plate of the

machine and that switch is “OFF” before connecting the tool to the power circuit.

Switching the machine on and off

To switch on: While holding with the left hand on the column and the right hand on the main handle,

Press the rocker switch to the right with the thumb of the right hand. Anticipate and be ready for the

start up torque when the machine ﬁrst starts.

To switch off: Press the rocker switch to the left. After the machine has been switched off, the

sanding disc will still rotate for a time. Take care that parts of your body do not come into contact with

the disc and do not set the machine down while it is still rotating!

Adjusting the rotation speed:

The speed of the machine is variable to suit different tasks. It can be

adjusted from 650/min up to 1600/min by using the thumb wheel. Using

the right thumb, turn in the downward (counterclockwise) direction to

increase the speed and in the upward (clockwise) direction to decrease

the speed. Generally, you should use the higher speed for fast stock

removal and the lower speed for more precise control.

Effective control of this powerful sander requires two-handed operation for maximum safety and

control.

The proper hold is to keep one hand on the main handle and the other hand on the sponge grip on the

column. It is vitally important to keep stable footing at all times, especially when standing on scaffolding

or stilts.

Starting and Stopping Tool

How to use the tool

1. Place the two D-Handle Brackets in place on the column forward of

the grip.

2. Thread in the 4 socket cap screws and tighten with the hex wrench

located in the D-Handle.

3. The D-Handle may then be placed in any of 3 angles. Position in the

desired angle then thread in the 4 socket cap screws.

4. Tighten with the hex wrench and when done, store the wrench in its

slot in the D-Handle.

1. Once the machine and vacuum cleaner are set up and all safety measures and equipment are in

place, begin by turning on the vacuum cleaner and then the machine. (If you are using a vacuum

cleaner with integrated switching, then simply turn the machine on.)

2. Begin sanding and carefully contact the work surface as lightly as possible-just enough to keep the

sanding head ﬂat against the surface.

3. The joints in the sanding head allow the sanding disc to follow the contours of the work surface.

4. The best technique is to use overlapping sweeps and keep the head in constant motion. Never

stop too long in any one place or there will be swirl marks. With experience it will be very easy to

create excellent results.

NOTE: Ensure that the sandpaper you are using is suited to the task. Overly coarse grit

paper may remove material too quickly to control. While overly ﬁne grit paper may clog

too often and not shape down the surface.

CAUTION: Take care to avoid pointed projections and nails, etc. This will wipe out the

sandpaper and probably damage the sponge pad as well.

Keep Tool Clean

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a

soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise

damage the material. Wear safety glasses while using compressed air. Clean the vacuum swivel

connector as too much dust will keep it from turning freely.

The carbon brushes

The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit.

NOTE: Checking and replacing the carbon brushes should be entrusted to a qualiﬁed

service center.

Mounting the Optional D-Handle

Sanding Operations

Maintenance

When new, the carbon brushes will last approximately 50 hours of running time or 10,000 on/off cycles.

Replace both carbon brushes when either has less than 6mm length of carbon remaining. To inspect or

replace brushes, ﬁrst unplug the machine. Carefully remove the 6 screws on the right side and 1 screw on

the left side to remove the right and left handle covers. The vacuum swivel connector will also come apart

when this is done. Remove the two screws holding on the Speed Control Unit (11) to allow access to the

Brush Holder screws (17). Unscrew the two Carbon Brush Holders and remove the Carbon Brushes.

NOTE: When putting the Carbon Brushes back into the Carbon Brush

Holders it is essential that both ﬂanges go back inside the holder.

NOTE: To reinstall the same brushes, ﬁrst make sure the brushes go

back in the way they came out. Otherwise a break-in period will

occur that will reduce motor performance and increase brush wear.

Replacing is the reverse of removal. Replace the Brush Holder screws, then

the Speed Control Unit screws. When Replacing the 2 handle cover halves

take great care that all wires are in place and not in a position to be pinched

when it is retightened. It is recommended that, at least once a year, you

take the tool to an Authorized Service Center for a thorough cleaning and

lubrication.

If the replacement of the power supply cord is necessary, this has to be done

by the manufacturer or their agent in order to avoid a safety hazard.
