MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and 
unplugged before attempting to perform inspection or 
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the 
like. Discoloration, deformation or cracks may result.
Lubrication
CAUTION:
• This servicing should be performed by Makita 
Authorized Service Centers only.
This tool requires no hourly or daily lubrication because it 
has a grease-packed lubrication system. It should be 
lubricated every time the carbon brushes are replaced. 
Send the complete tool to Makita Authorized Service 
Center for this lubrication service. (Fig. 14)
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. (Fig. 15)
Disconnect the connector by pulling them. (Fig. 16)
Loosen the five screws on crank cap and remove the 
crank cap. (Fig. 17)
Wipe out the old grease inside and replace with a fresh 
grease (30 g). Use only Makita genuine hammer grease 
(optional accessory). Filling with more than the specified 
amount of grease (approx. 30 g) can cause faulty 
hammering action or tool failure. Fill only with the 
specified amount of grease.
CAUTION:
• Be careful not to damage the connector or lead wires 
especially when wiping out the old grease.
To reassemble the tool, follow the disassembling 
procedure in reverse.
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 installing the handle. (Fig. 18)
Connect the connector firmly and then reinstall the 
handle.
To maintain product SAFETY and RELIABILITY, repairs, 
carbon brush inspection and replacement, any other 
maintenance or adjustment should be performed by 
Makita Authorized Service Centers, always using Makita 
replacement parts.

ENG901-1
• The declared vibration emission value has been 
measured in accordance with the standard test method 
and may be used for comparing one tool with another.
• The declared vibration emission value may also be 
used in a preliminary assessment of exposure.
WARNING:
• The vibration emission during actual use of the power 
tool can differ from the declared emission value 
depending on the ways in which the tool is used.
• Be sure to identify safety measures to protect the 
operator that are based on an estimation of exposure in 
the actual conditions of use (taking account of all parts 
of the operating cycle such as the times when the tool 
is switched off and when it is running idle in addition to 
the trigger time).
