5.How to replase grease

This machine is full air-tight construction to protect against dust and to prevent

lubricant leakage. Therefore, the machine can be used without lubrication for long periods. Replace the grease as described below.

◯Grease replacement period

You should look at the grease when you change the carbon brush. (See item 4 in the section MAINTENANCE AND INSPECTION.) Ask for grease replacement at the nearest HITACHI Authorized Service Center. Proceed for replacement of grease.

◯Grease replenishment

CAUTION: Before replenishing the grease, turn the power off and pull out the power plug.

(1)Disassemble the crank cover and thoroughly wipe off the old grease inside. (FIg. 21)

(2)Supply 30g (the standard volume to cover the connecting rod) of Hitachi Electric Hammer Grease A in the crank case.

(3)After replacing the grease, reassemble the crank cover securely. At this time, do not damage or lose the oil seal.

NOTE: The HITACHI Electric Hammer Grease A is of the lower viscosity type. When the supplied grease tube is consumed, purchase from a HITACHI Autorized Service Center.
