Safety

Work area safety

Keep work area clean and well lit. Cluttered or dark areas invite accidents.

Donotoperatepowertoolsinexplosiveatmospheres,suchasinthepresenceofammableliquids,gasesor

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

Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with

earthed(grounded)powertools.Unmodiedplugsandmatchingoutletswillreduceriskofelectricshock.

Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There

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

Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric

shock.

Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away

from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of electric shock.

If operating the power tool in damp locations is unavoidable, use a Ground Fault Circuit Interrupter (GFCI)

protected supply. Use of an GFCI reduce the risk of electric shock.

Personal safety

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

toolwhileyouaretiredorundertheinuenceofdrugs,alcoholormedication.Amomentofinattentionwhile

operating power tools may result in serious personal injury.

3. Afterllingtanks,dispensepolyureathroughmanifoldassemblywatching

ow.Anerrantstreamoutofoneorbothsidesofthemanifoldwillgenerally

indicate that there is a restriction in the manifold and disassembly and

cleaning should be performed.

4. Ifowisevenandequal,attachstaticmixingtiptoendofmanifold.

5. Dispense a small amount of material through the tip into waste container

to ensure thorough mixing in the tip. Then dispense small amount of

material onto cardboard or other disposable sheet to monitor cure. Allow

tosetfor10-15minutesoruntilsignicantcurehasbeenachievedpriorto

commencing. This will ensure proper ratio and cure of future material.

6. While waiting on test material to cure, remove static mixing tip and discard.

7. Pumpgrease(whitelithiumsuppliedwithpump)intottingsonmanifoldto

prevent cross contamination.

8. Uponconrmationoftestsamplecure,installnewstaticmixingtip.

9. Installllerintojointofcrackperproductinstallationguidelines.

Work Interruption:

1. If work is stopped for short term (5 minutes or so, to move pump, etc.)

periodically trigger applicator wand to dispense material every 30-45

seconds to ensure material in static mixing tip does not set.

2. If dispensing is stopped for longer term (lunch break, etc.) remove static

mixingtipanddiscard.PumpGreaseintottingsonthemanifoldas

described above. Upon commencement, re-install a new static mixing tip.

End of Day:

1. If possible, stop material placement when tanks are “nearly” empty

(material is down to within a couple of inches of the tank bottom). DO NOT

RUN tanks dry of polyurea or improper ratio and cure may result if one tank

empties slightly ahead of the other.

2. In case material is run to the bottom of the tank, remove static mixing tip

and dispense remaining material into a waste container until tanks are

empty and line sputters at the static tip.

 a.Fillbothtankswithhydraulicuidtoapproximately3inchesfromthe

bottom.

 b.Dispensehydraulicuidtopurgethepumpsandlines.Ensuresome

 c.Greasethettingsonthemanifoldandsecurefornextuse.

3. In case several inches of polyurea remains in the tank at day’s end AND,

pumpwillbeusedtoplaceadditionaljointllerthefollowingday,itcanbe

possible to leave the material in the machine overnight using the following

procedure. NOTE: Do not leave polyurea in the tanks or within the system

(tanks, pumps, lines, manifold) if material placement will not be performed

the following day.

a. Remove static mixing tip.

 b.Greasethettingsonthemanifoldandsecurefornextuse.

 c.FillIsosidetank(PartBforMetzger/McGuirejointllers,amber 

colored side) with Iso product to within a couple inches of the top

of the tank.

d. Press a new clean plastic bag, or similar plastic sheeting, over tank

and into top of product lapping excess plastic over the top sides of

the tank. By doing this, excess air potentially containing moisture or

humidity is forced away from the top of the polyurea Iso component.

e. Place tank lid over plastic sheeting and secure.

f. At next use, a thorough evaluation must be done as indicated in

the “Prior to Use” section to ensure no cross contamination exists

in the manifold.

Set-up and Operation

Next Day Use:

1. Itisalwaysadvisabletore-checkthemanifoldrstbyremovingthecheck

ball assembly and inspecting for clogs and also re-checking ratio by

dispensing a small amount of material into graduated plastic containers.

2. Before use, cure test should be performed by dispensing through the static

mixer onto a cardboard or plastic sheet and monitored for 10-15 minutes to

conrmcurepriortocommencementofllerplacement.

Troubleshooting

Problems During Dispensing Polyurea Joint Filler:

1. Materialowingslowly:

A. May occur when material temperature is cool and in the case of

cooler/freezerenvironments.Preheatmaterialand/orstoreoutside

 ofcooler/freezerarea.Forfreezerinstallations,tankheatersshould

be used to maintain a “pumpable” viscosity.

B. May occur if static mixing manifold has buildup or restriction in the

outletorice.Removepumplinesfromthemanifold,removettings,

plastic washer, check ball, and spring and ensure no buildup or

restrictionispresent.Inspectoutletoriceforrestrictionanddrillout

if buildup is present.

C. May occur if mixed material begins to “gel” inside of the static mixing

element (tip). This typically will occur when jumping from joint to

joint allowing mixed product to set inside the plastic mixer without

purging. Purging the static mixing element should be done

approximately every 45 seconds with most M/M products.

2. MaterialSTOPSowing:

A. Check main power supply to ensure voltage is entering the speed

control unit. Inside the control box cover located on the face of the

circuit board a GREEN LED light should be illuminated when proper

voltage is present. If indicator light is off (switch is on), check main

power supply cord to ensure power is being supplied to the control

box. Correct if necessary. If control box is receiving power and the

light on the front is OFF, check 12A ceramic fuse behind the control

box cover (left side of electrical panel). Replace if necessary.

B. If control box is receiving power and the LED light on the circuit board

is ON, check 8A MDL (slow burn) fuse behind the control box cover

(right side of electrical panel). DISCONNECT POWER before removing

or testing fuses! Replace if necessary. Burnt 8A MDL fuses will be

the primary cause for NO FLOW situations and will typically occur

when the motor is being placed under excess strain. Most common to

 occurwhendispensingincoldenvironmentsorfreezer/cooler 

installations.

C. If control box fuses are not “blown”, check trigger switch mechanism
