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
If an inferior grease is used, it may become too thick or too thin due to changes in temperature, and improper lubrication could result.
