Adjusting The Saw Prior To Use; Prior To Operation - Hitachi C 7D Handling Instructions Manual

5. Hold the charger firmly and pull out the battery.
NOTE:
After operation, pull out battery from the charger
first, and them keep the battery properly.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary phenomenon,
and normal time required for recharging will be
restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a
while.
CAUTION:
If the battery is charged while it is heated because
it has been lleft for a long time in a location subject
to direct sunlight or because the battery has just
been used, the pilot lamp of the charger lights up
green. In such a case, first let the battery cool, then
start charging.
When the pilot lamp flickers in red (at 0.2 – second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your
authorized Service Center.
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC24YFB is taken out, wait for a minimum of
3 seconds before reinserting it to continue charging.
If the battery is reinserted within 3 seconds, the
battery may not be properly charged.

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check that the working environment is suitable by
following the precautions.
2. Prepare a wooden work bench (Fig. 10)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on a work
bench when cutting. If a square block is utilized as
a work bench, select level ground to ensure it is
properly stabilized. An unstable work bench will
result in hazardous operation.
CAUTION:
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

CAUTION:
Pull out battery before doing any adjusting.
1. Adjusting the cutting depth (Fig. 11, Fig. 12)
To adjust cutting depth, loosen the clmap lever and,
while holding the base with one hand, move the
main body up and down to obtain the prescribed
cutting depth.
After adjusting to the prescribed cutting depth,
tighten the clamp lever securely.

2. Adjusting the angle of inclination (Fig. 13)
By loosening the wing bolt (A) on the inclined
gauge, the saw blade may be inclined to a maximum
angle of 45° in relation to the base. Always insure
that the wing bolt (A) is thoroughly tightened after
making the desired adjustment.
