MAINTENANCE
DAILY
Thoroughly remove dirt and oil from the engine compartment
and rammer. Clean or replace the air cleaner elements as
necessary. Check and retighten all fasteners as necessary.
Check the bellows for oil leaks. Repair or replace as needed.
200 - 300 HOURS (PRE-CLEANER)
Remove the element from the pre-cleaner (Figure 16) at the
top of the crankcase (body side) and clean it with cleaning
oil (kerosene).
Figure 16. Primary Air Cleaner
Lubricate the top element (yellow) with 2~5 cc of engine
oil SAE-30.
Lubricate bottom element (gray) with 7~9 cc of engine
oil SAE-30 and completely squeeze out the excess oil
from the element before installing.
AIR CLEANER
The air cleaner (Figure 17) on the engine side will hardly
be contaminated, if it is, clean the outer foam gray
element with cleaning solvent. Tightly squeeze outer
foam element to remove any excess solvent before
reinstalling.
Tap the paper filter element (Figure 17) several times on
a hard surface to remove dirt, or blow compressed air
[not exceeding 30 psi (207 kPa, 2.1 kgf/cm2)] through
the filter element from the air cleaner case side. NEVER
brush off dirt. Brushing will force dirt into the fibers.
Replace the paper filter element if it is excessively dirty.

MAIN SPRINGS LUBRICATION
The rammer main springs (Figure 18) should be
lubricated with five shots of grease with a hand grease
gun after each eight (8) hours of use.
Use MQ HIGH TEMPERATURE GREASE, P/N GRS2
or its equivalent.
Equivalent greases include Shell Darina or Texaco
Thermatex, both of which have a bentone base and
EP-2 rating.
If an inferior grease is used, it may become too thick or
too thin due to changes in temperature, and improper
lubrication could result.
