Depth gauge
Fig.20
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the clamp screw and adjust the
depth gauge to the desired depth. After adjusting,
tighten the clamp screw firmly.
NOTE:
The depth gauge cannot be used at the position
•
where the depth gauge strikes against the gear
housing/motor housing.
OPERATION
Hammer drilling operation

Set the change lever to the
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at
an idle, then remove the bit partially from the hole. By
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
CAUTION:
When the bit begins to break through concrete or if
•
the bit strikes reinforcing rods embedded in
concrete, the tool may react dangerously. Maintain
good balance and safe footing while holding the
tool firmly with both hands to prevent dangerous
reaction.
Blow-out bulb (optional accessory)

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.

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.

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.

Reinstall the crank cap and tighten with the screwdriver.
Connect the connector and reinstall the handle.

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.
