(2) As shown in Fig. 8, carry out lubrication around the
blade holder on a periodic basis by use of cutting
fluid, etc.

NOTE:
Continued use of the tool without cleaning and
lubricating the area where the saw blade is installed
can result in some slack movement of the lever due
to accumulated sawdust and chips. Under the
circumstances, pull a rubber cap provided on the
lever in the direction of an arrow mark as shown
in Fig. 9 and remove the rubber cap from the lever.
Then, clean up the inside of the blade holder with
air and the like and carry out sufficient lubrication.
The rubber cap can be fitted on if it is pressed firmly
onto the lever. At this time, make certain that there
exists no clearance between the blade holder and
the rubber cap, and furthermore ensure that the
saw-blade-installed area can function smoothly.

CAUTION:
Do not use any saw blade with a worn-out blade
hole. Otherwise, the saw blade can come off,
resulting in personal injury. (Fig. 10)

(3) After adjusting the base installing position, tighten
the base setting screw with the attached hexagonal
bar wrench completely.
9. Adjusting the blade reciprocating speed
This unit has a built-in electronic control circuit that
makes it possible to adjust the variable speed of
the saw blade by pulling a switching trigger. (Fig.
14)
If you pull the trigger further in, the speed of the
blade accelerates. Begin cutting at a low speed to
ensure the accuracy of your target cut position.
Once you've obtained a sufficient cutting depth,
increase the cutting speed.
CAUTION
Although this unit employs a powerful motor,
prolonged use at a low speed will increase the load
unduly and may lead to overheating. Properly adjust
the saw blade to allow steady, smooth cutting
operation, avoiding any unreasonable use such as
sudden stops during cutting operation.

HOW TO USE

CAUTION
Avoid carrying it plugged to the outlet with your
finger on the switch. A sudden startup can result
in an unexpected injury.
