If it is hard to turn the gear shift dial, turn the chuck
slightly in either direction and then turn the gear shift
dial again.
HOW TO USE
1. Switch operation
䡬 When the trigger is depressed, the tool rotates. When
the trigger is released, the tool stops.
䡬 The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly
and increases as the trigger switch is pulled more.
䡬 The desired rotation speed can be pre-selected with
the speed control dial.
Turn the speed control dial clockwise for higher speed
and counterclockwise for lower speed (Fig. 8).
䡬 Pulling the trigger and pushing the stopper, it keeps
the switched-on condition which is convenient for
continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
CAUTION
If the L-side of push button is pressed for reverse bit
rotation, the stopper cannot be used.
2. Drilling
䡬 When drilling, start the drill slowly, and gradually
increasing speed as you drill.
䡬 Always apply pressure in a straight line with the bit.
Use enough pressure to keep drilling, but do not
push hard enough to stall the motor or deflect the bit.
䡬 To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last part of the hole.
䡬 If the drill stalls, release the trigger immediately,
remove the bit from the work and start again. Do not
click the trigger on and off in an attempt to start a
stalled drill. This can damage the drill.
䡬 The larger the drill bit diameter, the larger the reactive
force on your arm.
Be careful not to lose control of the drill because of
this reactive force.
To maintain firm control, establish a good foothold,
use side handle, hold the drill tightly with both hands,
and ensure that the drill is vertical to the material
being drilled.
Slip clutch mechanism
This unit contains a slip clutch that causes the gears
between the motor and drill bit to slip when an excessive
load is suddenly applied. The slip clutch protects the unit
from a large violent reaction the load might cause.
CAUTION
䡬 If the slip clutch triggers and stops the drill bit rotation,
quickly turn off the power switch.
䡬 Do not operate the unit in a way that frequently
triggers the slip clutch.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded efficiency, replace the
drill bits with a new one or resharpening 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
on this tool should ONLY be performed by a Hitachi
Authorized Service Center.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must
be returned to Hitachi Authorized Service Center for
the cord to be replaced.
6. Service parts list
CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the
tool to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
