Xinpu XP-R26DA Handling Instructions Manual - Lubrication
LUBRICATION
Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without
replacing the grease. Please contact the nearest service center for grease replacement when any grease is
leaking from loosened screw.
Further use of the rotary hammer with lock off grease will cause the machine to seize up reduce the
service life.
CAUTION:
A special grease is used with this machine, therefore, the normal performance of the machine may be
badly affected by use of other grease. Please be sure to let one of our service agents undertake
replacement of the grease.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit
with new ones or resharpen them without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig.19)
The motor employs carbon brushes which are consumable parts. When they become worn to or near
“wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor
will stop automatically.
At that time, replace both carbon brushes with new ones which have the same carbon brush
specification
shown in Fig.19
In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
5. Replacing a carbon brush (Fig.20)
{ Disassembling
(1) Loosen the six screws on the
main handle cover, and remove the main handle cove.
(2) Lift out the brush holder together with the carbon brush, while being very careful not to forcibly pull
the lead wires within the brush holder.
(3) Withdraw the insert piece, and remover the carbon brush from the brush holder.
{ Reassembling
(1) Place a new carbon brush into the insert piece, and connect the brush terminal to the carbon brush.
(2) Return the brush holder and other parts to their original positions, as illustrated in Fig.20
(3) Place the lead wire in the specified position. Be very careful not to allow the lead wire to contact the
armature or rotating parts of the motor.
(4) Replace the main handle cover, while being careful to ensure it does not pinch the lead wire, and
secure it firmly with the six screws.
CAUTION:
Should the lead wire be pinched by the main handle cover or come in contact with the armature or
rotating parts of the motor, a serious danger of electric shock to the operator will be created. Exercise
extreme caution in disassembling and reassembling the motor, following the above procedures exactly.
Do not attempt to disassemble any parts other than those necessary to effect replacement of the carbon
