Maintenance - Makita HM0871C Betriebsanleitung

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 four 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 four screws on crank cap and remove the
crank cap cover. (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.

• 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).
