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.

1.Grease replacement period

After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the nearest HITACHI Authorized Service Center. Proceed for replacement of grease.

2.Grease replenishment

CAUTION:

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

(1)Remove the crank case cover and wipe off the grease inside.

(2)Apply 0.7 oz (20 g) of HITACHI Electric Hammer Grease A (standard accessory, contained in tube) to the crank case.

As the tube contains 1 oz (30 g) of grease, supply 2/3 of the contained grease.

(3)After replenishing the grease, install the crank case securely.

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.
