(2) Driving in wood screws
◯Prior to driving in wood screws, make pilot holes suitable for them in the wooden board. Apply the bit to the screw head grooves and gently drive the screws into the holes.
◯After rotating the rotary hammer at low speed for a while until the wood screw is partly driven into the wood, squeeze the trigger more strongly to obtain the
optimum driving force.
CAUTION
Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood into consideration. Should the hole be excessively small or shallow, requiring much power to drive the screw into it, the thread of the wood screw may sometimes be damaged.
8. How to use the drill bit (taper shank) and the taper shank adapter
(1)Mount the taper shank adapter to the rotary hammer (Fig. 19).
(2)Mount the drill bit (taper shank) to the taper shank adapter (Fig. 19).
(3)Turn the switch ON, and drill a hole in prescribed depth.
(4)To remove the drill bit (taper shank), insert the cotter into the slot of the taper shank adapter and strike the head of the cotter with a hammer supporting on a rests (Fig. 20).

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 form 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
For your continued safety and electrical shock protection, carbon brush inspection and replacement
