EM-70 PLASTER/MORTAR MIXER — MAINTENANCE (MIXER)
Inspect Tooth Contact between Main Gear and Drive
Pinion
1. Coat 3 or 4 teeth at 3 different positions on the main
gear with yellow paint.
2. Rotate the drive pulley in both directions.
3. Inspect the tooth pattern.
4. If gear teeth are not contacting properly (Figure 32),
adjust pillow block to correct the problem.

Gear Lubrication
The surface of the pinion and main gear (Figure 33) should
be very lightly greased.
Figure 33. Pinion and Bull Gear Lubrication
NOTE
Excess grease will accumulate contaminates and cause
premature wear.
PAGE 32 — EM-70 PLASTER/MORTAR MIXER — OPERATION MANUAL — REV. #1 (008/10/04)
Grease main and pinion gears
250 hours
every
operation . IMPORTANT!
Avoid over-greasing.
Grease Fittings (Zerk) Maintenance (Electric Motor)
1. There are two grease (Figure 34) fittings at each end of
the electric motor that will require lubrication. Lubricate
these fittings about every 16 months.
2. Use Poleyrex EM (Exxon Mobil) or equalivant lubricant.
Clean grease fitting, apply grease gun to fitting (1/2
shot). Remember too much
grease or injecting grease too
quickly can cause premature
bearing failure. Slowly apply the
recommended amount of grease,
taking a miniute or so to apply.

Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical compo-
nents of the trailer. When specifying or replacing the trailer
wheels it is important the wheels, tires, and axle are prop-
erly matched.
WARNING WARNING WARNING
WARNING WARNING
DO NOT attempt to repair or modify a
wheel. DO NOT install an inter-tube to
correct a leak through the rim. If the
rim is cracked, the air pressure in the
inter-tube may cause pieces of the rim to explode (break-
off) with great force and can cause serious eye or bodily
injury.
Tires Wear/Inflation
Tire inflation pressure is the most important factor in tire life.
Pressure should be checked cold before operation. DO NOT
bleed air from tires when they are hot. Check inflation pres-
sure weekly during use to insure the maximum tire life and
tread wear.
