FUNCTIONAL DESCRIPTION
CAUTION:
•
Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Switch action
CAUTION:
•
Before plugging in the tool, always check to see that the switch lever actuates properly and returns to the "OFF"
position when released.
1.
Switch lever
To start the tool, simply squeeze the switch lever. Release the switch lever to stop.
NOTE:
•
Blows at no load per minute becomes smaller than those on load in order to reduce vibration under no load, but
this does not show trouble. Once operation starts with a bit against concrete, blows per minute increase. When
temperature is low and there is less fluidity in grease, the tool may not have this function even with the motor rotating.
Indicator lamps
1.
Power-ON indicator lamp (green)
2.
Service indicator lamp (red)
The green power-ON indicator lamp lights up when the tool is plugged. The indicator lamp is lit but the tool does not start
even if the tool is switched on, the carbon brushes may be worn out, or the controller, the motor or the ON/OFF switch
may be malfunction. The red service indicator lamp flickers up when the carbon brushes are nearly worn out to indicate
that the tool needs servicing. After some period of use, motor will automatically be shut off.
ASSEMBLY
This tool accepts bits either with or without a collar on its shank. To install the bit, follow either procedure (1) or (2)
described below.
(1)
For bits with a collar
Pivot the tool retainer downward (approx. 60 degrees). Insert the bit into the tool holder until it stops. Return the tool
retainer and secure the bit.
(2)
For bits without a collar
Pivot the tool retainer upward (approx. 60 degrees). Face the notched portion of the bit upward. Insert the bit into the tool
holder until it stops. Pivot the tool retainer further until it stops at the tool holder. To remove the bit, follow the installation
procedure in reverse.
CAUTION:
•
Always assure that the bit is securely retained by attempting to pull the bit out of the tool holder after installing the
bit.
•
If inappropriate installation method is selected, the bit cannot be secured.
OPERATION
Chipping/Scaling/Demolition
CAUTION:
•
Keep well-balanced posture when holding the heavy tool before / during / after operation to avoid personal
injuries.
•
Secure debris in case of breaking it into smaller pieces.
•
Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.
•
Do not pull out the tool if stuck. Instead, break the work around the bit tip.
•
Be sure to place the tool on the stable floor or ground after use.
