1 Please observe the following1.1 Emphasized Sections☞WARNING!Refers to safety regulations and required safety measures that protect the operator or otherpersons from injury or danger to life.Caution!Emphasizes what must be done or avoided so that the unit or other property is not damaged.Notice:Gives recommendations for better handling of the unit during operation or adjustment as well asfor service activities.1.2 For Your Safety• For safe and successful operation of this machine, read these instructions completely. If theinstructions are not observed, the manufacturer can assume no responsibility.• Observe general safety regulations for the handling of chemicals such as Loctite adhesivesand sealants. Observe the manufacturer’s instructions as stated in the Material Safety DataSheet (MSDS).• While under warranty, the machine may be repaired only by an authorized Loctite servicerepresentative.• Wear heat resistant leather gloves when operating or maintaining a hot machine.• Always use extreme care when using the Hysol ® Wheel Coater.• Roll temperature and adhesive may reach 400°F. Avoid skin contact with the roll.• If molten adhesive is accidentally deposited on skin, immerse immediately in cold water.DO NOT ATTEMP TO REMOVE LARGE AMOUNTS OF GLUE FROM SKIN WITHOUTFIRST SECURING PROPER MEDICAL ATTENTION.• Check that the surface to be coated will not melt or be damaged by the temperature of theadhesive and roll.• Do not use the machine in damp or wet areas.• Make sure the machine is properly positioned and secured to a sturdy, stable work surface toavoid tipping and spilling hot melt adhesive onto the machine operator.• Do not operate the machine with the pot cover in the raised position. Keep cover in place overmolten adhesive.• Always us a properly grounded 120V outlet. Do not remove the grounding prong from themachine electrical plug.1


1 Please observe the following (continued)• Allow machine to cool and adhesive to solidify before attempting to move the machine.• A qualified electrician or appliance repair person should perform machine repair.• Do not overfill adhesive pot. Molten adhesive should never be above the 1 ⁄2" ledge near thetop of the pot.1.3 Items SuppliesHysol ® Wheel CoaterInstruction manual5 spare fuses1 tube grease2 Description2.1 Description of MachineThe Hysol ® Wheel Coater (98038) is a bulk hot melt adhesive transfer machine. The Hysol ®Wheel Coater is used to apply a continuous film of hot melt adhesive to the surface of a part.The Wheel Coater is made up of an adhesive reservoir (6.5" wide x 10" long x 2" deep), three350-watt heaters and a transfer roller, which is driven by a variable speed electric motor. Thethickness of the adhesive film is fully adjustable and a thermometer is used to indicate reservoirtemperature. The variable speed motor and film thickness control greatly contributes to increaseproductivity of hot melt adhesive applications.2.2 Theory of OperationThe adhesive is applied by passing the surface of the part over a rotating roller. A thin film ofadhesive is transferred from the roller to the part. The roller is six inches in length and is partiallysubmerged in a pool of molten adhesive. With each rotation the roller is recoated. The transfersurface, of the roller, is knurled to hold a greater volume of adhesive. The thickness of theadhesive is controlled by means of an adjustable blade doctor. The adhesive temperature andthe viscosity of the adhesive formulation also affect the thickness of the film.2

5 Operation5.1 Set Up• Place the Hysol ® Wheel Coater on a level, heavy-duty bench and preferably one withadjustable legs.• Adjust the height of the table so the working height of the machine is comfortable.• Plug the power cord into a properly grounded 120V, 15-amp outlet.5.2 Start Up• Fill reservoir to a depth of 1" minimum and 2" maximum. Do not fill above the 1 ⁄2" ledge nearthe top of the pot. Maintain the level within this range during operation.• Turn rotary switch, on motor speed control (item 2), to the off position.• Plug power cord into properly grounded 120V, 15 amp outlet.• Flip toggle switch (item 1) to “ON” position. Red indicator light will come on.• Allow machine to warm up 30 minutes. Observe thermometer.• Add additional pellets as required to bring the fill level to between 1" and 2" deep.Caution! DO NOT ATTEMPT TO ACTIVATE THE COATING ROLL BEFORE OPERATINGTEMPERATURE IS ATTAINED. To do otherwise, will cause a motor overload, which willblow the fuse (F1).• Turn rotary switch, on the motor speed control, (item 2) clockwise to start the roller turningslowly. For a new unit it may be necessary to turn the rotary switch 50% of scale to startrotation. Turn the switch to a higher number to increase the rate of rotation.5.3 Shut Down• Always turn off the motor speed switch first. This sequence will help ensure that the roller isnot accidentally started with a cold machine.• Flip the power switch to the “Off” position.5


5 Operation (continued)5.4 Film Thickness Adjustment• Adjusting the clearance between the doctor blade and the roller can change film thickness onthe roller.• Loosen the 4 machine screws, which secure the doctor blade.• Place a feeler gauge between the roll and blade at one end of the roll.• Tap the blade lightly against the feeler gauge.• Lightly snug the end most screw.• Move the gauge to the other end of the roll and repeat.• Snug all four screws down. Do not over tighten.5.5 Temperature adjustment• The operating temperature of the machine is factory set at 375°F. This setting should besufficient for most EVA adhesives. For other types of adhesives refer to the data sheet for theadhesive application temperature or call Technical Service for assistance.• The temperature thermo switch set point shaft is not intended for operator adjustment and isaccessible only by removing the sheet metal cover from the adhesive pot. The thermo switchis located at the roller end of the reservoir.• A quarter-turn clockwise of the set point shaft will increase the operating temperature about75°F. Wait at least 15 minutes for the temperature to stabilize. After 1 hour of operation, checkthe temperature again.☞Notice: Do not exceed 450°F.6


6 Care, Cleaning, and Maintenance6.1 Char RemovalIf the Hysol ® Wheel Coater is over heated a brown or black flaky crust will form on exposedsurfaces of the glue pot. This is charred adhesive that can be removed using the followingprocedure.• Wear heat resistant leather gloves.• Warm the machine to operating temperature.• Pour out excess adhesive.• Scrape off excess adhesive and char with a wood tongue depressor.• Allow machine to cool.• Use a paintbrush to apply a coating of solvent-based paint remover to remaining char.• Allow paint remover solvent to soak on the char. It may be necessary to allow paint removerto soak overnight.• Remove softened char and reapply paint remover as required.6.2 ClutchThe clutch is factory set and seldom needs adjustment. In the event that additional torque isneeded the following is the torque setting procedure:1. Remove chain guard.2. Remove set screw on clamping nut.3. Use square socket on thread end of hub to secure shaft.4. Tighten clamping nut against Belleville washer. Do Not completely flatten Belleville washer.5. Replace set screws.6. Replace chain guard.BELLVILLE WASHERSHAFTSPROCKETFRICTIONMATERIALSET SCREWCLAMPING NUTFigure 27


6 Care, Cleaning, and Maintenance (continued)6.3 Drive Chain• Remove chain guard and oil chain monthly if machine is used continuously.• If chain is loose, loosen motor mount screws and slide motor to tighten.6.4 Fuse, Motor Controller☞• The motor controller fuse will blow in the event of a motor overload.• Before replacing fuse check for cause of motor overload.Notice: Pot must be hot.• Remove drive chain and check for free rotation of roll.• Replace the motor control fuse with a Bussman ABC 3AMP Fuse , #6F041, 250 VOLT, FuseHolder Code G, Ceramic Body Fast Acting type AGC 3Amp or equivalent.6.5 Drive Motor• Inspect motor brushes every 300 hours.• Replace brushes when worn down to approximately 1/4" length.8
