Functional Description; Replacing The Blade - Hitachi CH 10DL Handling Instructions Manual

○ When the pilot lamp fl ikers (at 0.2-second intervals),
check for and take out any foreign objects in the charger's
battery connector. 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 confi rm that the battery being charged with UC10SFL
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.

FUNCTIONAL DESCRIPTION

1. Battery Level Warning Lamp
The battery level can be checked by pulling the trigger
switch while the power tool is in a no-load state. The
battery level warning lamp lights when the battery power
is very low. If this happens, charge the battery. (Fig. 4)
NOTE
○ The level at which the battery level warning lamp lights
may vary due to the ambient temperature, characteristics
of the battery, etc. and is intended only as a guide.
○ The battery level warning lamp may light when the power
tool is overloaded. This does not mean that the battery
power is very low.
Be sure to check the battery level while the tool is in a
no-load state.
2. Lock Off button (Fig. 5)
WARNING
Never lock the Lock Off button in depressed position.
Pulling back the switch would then cause the tool to
suddenly start operating, which could result in injury.
The tool will not start unless the Lock Off button is
pressed while the switch is pulled back.
The Lock Off button can be engaged by pressing it either
from the right or left.
When the switch is released, the Lock Off button
automatically disengages to prevent inadvertent motor
startup.

REPLACING THE BLADE

The blade is a consumable that has to be replaced with a
new blade when it loses sharpness.
Follow the steps below to replace the blade.
The tool shown in the illustration is the shrub shear, and it is
used in examples to explain features it shares with the grass
shear.
Before replacement, turn the switch on and off until the teeth
in the upper blade are positioned over the openings between
the teeth in the lower blade.
At this time, be careful of the moving blade.
WARNING
Be sure to turn off the power switch and remove the
battery from the tool to prevent accidents.
CAUTION
Before blade replacement, be sure to use gloves and
attach the blade case or blade cover to prevent the blade
from coming into direct contact with your hands or face.
1. Remove the blade (Fig. 13)
(1) Turn the tool over, remove the four screws using a Phillips
screwdriver, remove the bottom plate and the blade (with
blade case).
(2) Remove the remaining crank holder and crank cam (A)
from the tool. The grease used may cause the crank
holder and crank cam (A) to stick to the blade.
(3) Remove any chips and other debris from inside the
housing.
2. Getting a new blade ready
Taking care to prevent injury from contact with the blade,
adjust the crank cam position as shown in Fig. 14.
This places the teeth in the upper blade over the openings
in the teeth in the lower blade.
3. Attach the crank cam and crank cam holder to the
blade (Fig. 15)
The same type of crank cam holder is used in the shrub
shear and the grass shear. Use the crank holder installed
in the product.
4. Attach the new blade
(1) Align the pin on the tool with the center hole in the crank
holder. (Fig. 16)
(2) When the hexagonal part in the crank holder and the
grooves in the gear do not align, fi ne adjust so that the
crank holder aligns with the gear grooves. (Fig. 17)
(3) Turn over the tool making sure that the blade does not
fall out, attach the bottom plate and secure it with the 4
screws. (Fig. 18)
NOTE
Be sure to check blade operation after it has been
attached. The blade and the crank cam has not been
properly fi tted if the blade does not operate correctly. Do
the instructions over from the beginning.
