(3) When the hole depth reaches approximately 5mm, the hole position can be determined. Then
remove the dill bit from the core bit and continue the hole drilling job.
CAUTION:
When removing the dill bit, always disconnect the plug from the receptacle.
3. How to dismount the core bit
○
By holding the rotary hammer (with the core bit inserted) in an upward position, drive the rotary
hammer to repeat impact operation two or three times, whereby the screw is loosened and the rotary
hammer becomes ready for disassembly.
(Fig. 15)
○
Remove the core bit shank from the rotary hammer, hold the core bit with one hand, and strongly
strike the head of the SDS max shank portion of the core bit shank with a manual hammer two or
three times, whereby the round head screw is loosened and the rotary hammer is ready for
disassembly.

HOW TO REPLACE GREASE
This machine is of full air-tight construction to protect against dust and to prevent lubricant leakage.
Therefore, the machine can be used without lubrication for long periods. Replace the grease as
described below.
1. Grease replacement period
After purchase, replace grease after every 6 months of usage. Ask for grease replacement at the
nearest XINPU Authorized Service Center. Proceed for replacement of grease.
2. Grease replenishment
CAUTION:
Before replenishing the grease, turn the power off and pull out the power plug.
(1) Remove the oil tank cover and wipe off the grease inside. (Fig. 17)
(2) Supply 30g of XINPU Electric Hammer Grease (Standard accessory, contained in tube) to the
crank case.
(3) After replenishing the grease, install the oil tank cover securely.
NOTE:
The XINPU Electric Hammer Grease is of the low viscosity type. If necessary purchase from an
XINPU Authorized Service Center.
MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of a dull tool will degrade efficiency and cause possible motor malfunction, sharpen or
replace the tool as soon as 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
The Motor employs carbon brushes which are consumable parts. When they become worn to or near
the “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 of specification with standard. In addition, always keep carbon brushes clean
and ensure that they slide freely within the brush holders.
