INSPECTION AND PREPARATION
PRIOR TO USE
Prior to use, make the following inspection and preparation.
WARNING
○ Ensure that the power source to be utilized conforms
to the power requirements speci fi ed on the product
nameplate.
○ To prevent accidents, always perform steps 1 to 5
ensuring the plug is disconnected from the receptacle.
○ Do not secure the lock-o ff button while it is pressed.
If the switch is accidentally engaged, the unit may
unexpectedly start and injury may occur.
1. Ensuring the switch is o ff
○ Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
○ When the switch is engaged while pressing the lock-
o ff button, the unit switches on, and when the switch is
released, the unit switches o ff .
2. Checking the extension cord
When the work area is remote from the power source,
use an extension cord of su ffi cient thickness and rated
capacity. The extension cord should be kept as short
as practicable.
3. Checking the saw chain tension
○ If the saw chain tension is incorrect, there is a risk of
damage to the saw chain or guide bar and malfunction.
Referring to steps 5 to 7 “Installing (replacing) saw
chain,” ensure an appropriate tension is set.
○ While the saw chain is still new, it is particularly
stretchy, so periodically check the tension and adjust
as required.
○ Also check the knob is securely tightened.
4. Checking operation of chain brake (Fig. 13)
WARNING
○ Although the chain brake is an emergency stop device,
this is not completely reliable. Operate carefully to
avoid the risk of kickback.
○ The chain brake is intended for use in emergencies and
when starting up. Do not use it indiscriminately.
○ To avoid impaired movement of the chain brake due to
buildup of sawdust etc., clean regularly.
○ The chain brake is an important component to ensure
safe use.
If you have any concern regarding the brake operation,
request repair from your Hitachi Authorized Service
Center.
