MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

maintenance.

Lubrication

CAUTION:

• This servicing should be performed by Makita

Authorized or Factory Service Centers only.

This tool requires no hourly or daily lubrication because it

has a grease-packed lubrication system. Lubricate the

tool every time the carbon brushes are replaced. (Fig. 24)

Run the tool for several minutes to warm it up. Switch off

and unplug the tool.

Loosen the six screws and remove the handle. Note that

the top screws are different from other screws.

Disconnect the connector by pulling them. (Fig. 25)

Loosen the screws and remove the change lever.

(Fig. 26)

Remove the crank cap cover.

Remove the control plate. (Except for model HR5211C.)

(Fig. 27)

Loosen the six screws with a screwdriver and remove the

crank cap. Rest the tool on the table with the bit end

pointing upwards. This will allow the old grease to collect

inside the crank housing. (Fig. 28)

Wipe out the old grease inside and replace with a fresh

grease (60 g). Use only Makita genuine hammer grease

(optional accessory). Filling with more than the specified

amount of grease (approx. 60 g) can cause faulty

hammering action or tool failure. Fill only with the

specified amount of grease. (Fig. 29)

Reinstall the crank cap and tighten with the screwdriver.

Connect the connector and reinstall the handle. (Fig. 30)

CAUTION:

• Do not tighten the crank cap excessively. It is made of

resin and is subject to breakage.

• Be careful not to damage the connector or lead wires

especially when wiping out the old grease or installing

the handle.

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be

performed by Makita Authorized Service Centers, always

using Makita replacement parts.
