HOW TO USE

CAUTIONS
Do not remove the insulation cover. It is necessary
to support the body of the tool.
During operation, the base of the tool should be
pressed against the material, as shown in Fig. 6,
herein. If the tool is not properly pressed against
the maerial, the blade may be damaged by vibration.
1. Cutting metallic materials
Ensure the material is firmly held in position during
operation. Always use an appropriate cutting agent
(spindle oil, soapy water, etc.). When a liquid cutting
agent is not available, apply grease to the material
to be cut.
2. Cutting lumber
When cutting lumber, ensure that the wooden
material is firmly fixed in position.
3. Sawing curved lines
Use a No. 6 or No. 7 blade (optional accessories)
as described below.
For metal-working - No. 6
For wood-working - No. 7
When sawing a small circular arc, reduce the feeding
speed of the machine.
4. Cut off guide for cutting pipe (optional accessory)

SELECTION OF BLADES
To ensure maximum operating efficiency and results, it
is very important to select the appropriate blade best
suited to the type and thickness of the material to be cut.
Three types of blades are provided as standard
accessories.
The blade number is engraved in the vicinity of the
mounting position of each blade. Select appropriate
blades by refering to Tables 1 and 2 below.

MAINTENANCE AND INSPECTION

1. Inspecting the blade
Continued use of a dull or damaged blade will
result in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with
a new one as soon as excessive 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.
