ADJUSTMENT
To avoid personal injury, always turn off engine/motor and wait for all motion to stop before making
adjustments or repairs.
RUBBER WIPER BLADES
Adjust rubber wipers so they fit snugly against the drum but not to the point that they fold over when the blades rotate.
ENGINE/MOTOR DRIVE
See Figure 4 (800MP & 1200MP Models)
1. Check the roller chain regularly so with one strand tight, the
slack strand can be moved approximately one half of an inch. If an
adjustment is required, loosen the bolts on the pillow block bearings
and slide the pillow block/shaft assembly toward or away from the
driven sprocket as necessary.
2. Align the pulleys so the belts will run straight. Make sure all set
screws are tightened on the pulleys when you are finished.
3. To set the belt tension, loosen the bolts that hold the engine or motor
to the mounting plate. Move the clutch lever to the engaged position.
Slide the engine or motor in the mounting slots until the belt is tight, then slide the engine or motor back approximately
1/4". Tighten the mounting bolts.
4. Adjust belt fingers so they allow disengagement of the drive, but they must not touch the belt when the clutch is
disengaged.
STORAGE
For short term storage, clean the mixer and store in a dry place. If the mixer is not to be used for an extended period of time,
service the mixer completely and store in a dry place.
1. Refer to the engine/motor instructions for storage instructions.
2. Cover exposed metal surfaces with a thin coat of SAE 30 weight engine oil.
3. Lubricate per instructions outlined in the LUBRICATION section (page 12).
WARNING!
CLEANING THE MIXER
To avoid personal injury, always turn engine/motor off and wait for all motion to stop before cleaning.
To achieve satisfactory performance from the mixer, it is essential to give the drum reasonable care. Clean the mixer after
each use, before the mortar dries and becomes hard. Never permit mortar to harden on either the inside or outside of the
drum. Do not pound or dent the drum as this impairs mixing efficiency and can cause spot wear on the drum surface. Spray
the entire unit off after each use.
It is important to keep the inside of the mixing drum free of hardened mortar. After discharging the last batch of mortar each
day, add a pailful of water and two shovelfuls of gravel to the drum. This will scour the inside of the drum. Mix for about two
minutes, discharge and rinse the drum with water.
WARNING!
SERVICING THE MIXER
1. Clean mixer thoroughly.
2. Check all bearings and seals for proper operation.
3. Check mixing arms, blades, and wipers for damage or wear.
4. Any damaged or excessively-worn parts should be replaced.
