Selecting the cutting action (Fig. 7)
This tool can be operated with an orbital or a straight line (up and down) cutting action. The orbital cutting action
thrusts the blade forward on the cutting stroke and greatly increases cutting speed.
To change the cutting action, just turn the lever to the desired cutting action position. Refer to the table below
to select the cutting action.

Switch action (Fig. 8)
CAUTION:
Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the ''OFF'' position when
released. Pulling the trigger hard when the lock-off
button is not pressed causes switch damage.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided. To start the tool,
depress the lock-off button and pull the switch trigger.
Release the switch trigger to stop.
Speed adjusting dial (Fig. 8)
The tool speed can be infinitely adjusted between 500
and 2,800 (Model 4331D), 500 and 2,600 (Model
4333D) strokes per minute by turning the adjusting
dial. Higher speed is obtained when the dial is turned
in the direction of number 5; lower speed is obtained
when it is turned in the direction of number 1. Refer to
the table below to select the proper speed for the
workpiece to be cut. However, the appropriate speed
may differ with the type or thickness of the workpiece.
In general, higher speeds will allow you to cut work-
pieces faster but the service life of the blade will be
reduced.
Workpiece to be cut
Wood
Mild steel
Stainless steel
Aluminum
Plastics
CAUTION:
The speed adjusting dial can be turned only as far as
5 and back to 1. Do not force it past 5 or 1, or the
speed adjusting function may no longer work.

Operation (Fig. 9)
CAUTION:
• Check carefully that the blade is adequately
secured in position before inserting the battery into
the tool.
• Always hold the base flush with the workpiece.
Failure to do so may cause blade breakage, result-
ing in a serious injury.
Turn the tool on and wait until the blade attains full
speed. Then rest the base flat on the workpiece and
gently move the tool forward along the previously
marked cutting line. When cutting curves, advance
the tool slowly.
Bevel cutting (Fig. 10 & 11)
CAUTION:
Always remove the battery from the tool before mak-
ing any adjustments.
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right).
Loosen the bolt on the back of the base with the hex
wrench. Move the base so that the bolt is positioned
in the center of the cross-shaped slot in the base. Tilt
the base until the desired bevel angle is obtained. The
edge of the motor housing indicates the bevel angle
by graduations. Check the contact between the back
edge of the blade and the roller, then tighten the bolt
to secure the base.
Front flush cuts (Fig. 12)
Loosen the bolt on the back of the base with the hex
wrench, then move the base all the way back. Then
tighten the bolt to secure the base.
