2.1 This machine is designed and manufactured ONLY for grinding lawn mower reels, rollers,

groomers and verticut units, and MUST NOT be used for any other purpose.

2.2 This machine should be installed, operated and maintained by competent personnel who

have received adequate training.

2.3 Before carrying out any work on the machine, other than grinding, ALWAYS SWITCH OFF

the main electrical supply, or remove the power lead from its socket.

2.4 ALWAYS operate the machine with the guards in position.

2.5 NOISE - Owing to the widely varying conditions of use, noise emissions may vary

considerably. There may be occasions when the safe noise level may be exceeded (see

note on noise emission). In this case adequate ear protection MUST be worn.

2.6 NEVER t or use a grinding wheel (or other spares) other than those supplied specically

for use on the EXPRESS DUAL (Warranty will be invalidated).

2.7 NEVER t or use a grinding wheel which has been dropped or subjected to any other form

NOTE: Grinding wheels should be tted ONLY by competent, trained personnel.

2.8 NEVER leave rags or tools on the machine or wear any loose clothing or other articles

which could be caught in moving components.

2.9 NEVER allow any combustible materials to be placed on or around the machine.

3. Set Up and Installation

Fig: 3.2

3.1 Handling

If the machine is crated, it can be moved by a suitable fork lift truck or pallet truck under

the pallet (skid). Once the lid and sides of the crate are removed, a fork lift truck may be

used under the lifting members of the machine chassis.

The machine can be lifted off the pallet using suitable lifting tackle through 4 lifting eyes

(provided) tted at the points indicated on the top corners of the machine.

The total weight of the machine is indicated on the machine plate and also at the front of

this manual.

3.2 Location

The machine should be located in a well lit environment with adequate headroom. For

ideal operation, the machine should be accessible from the front, rear and at least one

side, with clearance around it as indicated in the sketch (Fig. 3.2).

3.3 Leveling

The machines should, ideally, be placed on a solid level oor, and this should be checked

by placing a spirit level on the table. Check the level in both directions. Steel shims should

be placed under the feet as necessary to ensure that the machine is rm and level. Bolt

holes are provided in the feet which can be used for xing down if required.

NOTE Ensure that the packing under the feet is correct before tightening the bolts, otherwise

twisting of the frame may occur.

3.4 Electrical Supply

USE A QUALIFIED ELECTRICIAN

The EXPRESS DUAL is supplied with a .55 kW ( HP) single phase main (grind) motor

plus 2 fractional HP motors, for spin and traverse.

Power connection to the machine is via plug and socket termination of the lead supplied.

Connection is at the rear of the main electrical control box on the right hand end of the

machine.

Ensure that any cable or conduit run to the machine does not constitute a hazard to the

operator or other personnel.

Machine should be connected to the supply via a 20A breaker.

The top of the reel and the top of the grinding wheel should both move away from the

front of the machine (i.e. both rotate clockwise when viewed from right hand end of the

machine). In this way, the reel and grinding wheel are moving in OPPOSITE DIRECTIONS

at the point of contact.

3.5 Preparation

If the machine has been

received in a crate, the handles

on the control wheels should be

removed from the underneath of

the control wheels and retted to

the top (see Fig. 3.5).

It is important that the protective

film on the main shaft is

removed prior to using the

machine. This can be done

using a WD40 or similar product

(not gas/petrol) and then drying

the shaft with a clean, dry cloth

so that the grinding wheel

assembly moves freely along

the whole length of the shaft.

A spray lubricant, such as WD40, should be applied to all bare metal surfaces and moving

parts; this includes the reversing bar and the shafts (along which the fork assembly

traverse, but NOT THE MAINSHAFT).

The mainshaft should be washed down as instructed in the maintenance section of this

manual. The feed control screws are normally coated with molycote, and may be washed

down with WD40 if required and recoated with molycote (or similar anti friction coating)

when dry.
