SHAFT SEALS
CAUTION:
IMPORTANT -DRUM HEAD SEAL CARE
Grease seals every
40 hours
of operation
using any grade #1 lithium base grease. Apply
grease until visible inside of mixing tub (over
grease). This will purge seal system of
contamination.
GEAR/CLUTCH REDUCTION ASSEMBLY LUBRICATION
The gear/clutch reduction assembly has two separate
compartments. Each of which must be filled with its proper
lubricant and checked at regular intervals.
The
clutch compartment
should be filled with a good grade of
number 30 SAE engine oil which can be poured through the
filler hole located just above the clutch inspection door on the
opposite side of the transmission. Fill the clutch compartment
with 30 SAE engine oil until it overflows the oil level plug located
on the shifter side of the clutch compartment . Check this oil level
every two or three months and add oil as required. Drain and
refill once a year.
The
reduction gear, upper compartment
should be filled with
number 90 SAE oil, as used in automobile transmissions. The
filler plug is at the top of the reduction gear case and the oil level
plug is on the same side of the case as the clutch lever. Fill the
reduction gear compartment with 90 SAE transmission oil until it
overflows the oil level plug. Check this oil level every two or
three months and add oil as required. Drain and refill once a
year.
PADDLE SHAFT BEARINGS
The paddle shaft in the MQ ESSICK EM120SM mixer rotates in
sealed ball bearings, which require no additional lubrication as
they are packed and sealed at the factory.
There is, on each end of the mixing drum, a zerk grease fitting
(pivot point). Grease these fittings once a week as they lubricate
the dumping mechanism of the mixing drum.
Failure
to lubricate
the zerk grease fittings once a week will cause the dumping
mechanism to stiffen, making the mixer hard to dump.
HARDWARE
Check all hardware on the mixer before starting. Periodically
inspect all hardware. Loose hardware can contribute to early
component failure and poor performance. Use Table 11 (Torque
Chart) as a general guideline and keep all hardware tight.
ENGINE OIL
1. If mixer's engine oil is low, fill engine crankcase with
lubricating oil through filler hole, but DO NOT overfill.
2. The oil listed in Table 7 is recommended to ensure better
engine performance. Use class CD or higher grade motor
oil.
AIR CLEANER (DRY TYPE)
1. Change the air cleaner every 500 hours. See Figure 12
for location of air cleaner.
FUEL FILTER/FUEL TANK
1. Change the fuel filter every 500 hours.
2. Siphon water out of fuel tank once a year.
CLEANING
ALWAYS make sure engine is OFF before cleaning the inside
of the drum. NEVER put hands, fingers or arms inside mixing
drum when engine is ON.
NEVER pour or spray water over engine.
For consistent performance, long life and high quality mixing,
thoroughly clean the mixer inside and out at the end of each
day’s operation. To prevent lumps of dried mortar from forming
and contamination of future batches, DO NOT allow a buildup of
materials to form on the blades or anywhere inside the drum.
