up or kickback if the power tool is restarted in the
workpiece.
9. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near
the line of cut and near the edge of the workpiece on
both sides of the wheel.
10. Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to safety
rules for the subject product. MISUSE or failure to
follow the safety rules stated in this instruction
manual may cause serious personal injury.
IMPORTANT SAFETY
INSTRUCTIONS
FOR BATTERY CARTRIDGE
1. Before using battery cartridge, read all
instructions and cautionary markings on (1)
battery charger, (2) battery, and (3) product using
battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively shorter,
stop operating immediately. It may result in a risk
of overheating, possible burns and even an
explosion.
4. If electrolyte gets into your eyes, rinse them out
with clear water and seek medical attention right
away. It may result in loss of your eyesight.
5. Always cover the battery terminals with the
battery cover when the battery cartridge is not
used.
6. Do not short the battery cartridge:
(1) Do not touch the terminals with any
conductive material.
(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a
breakdown.
7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 °C (122 °F).
8. Do not incinerate the battery cartridge even if it is
severely damaged or is completely worn out. The
battery cartridge can explode in a fire.
9. Be careful not to drop or strike battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room
temperature at 10 °C - 40 °C (50 °F - 104 °F). Let a
hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge
when you do not use it for more than six months.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
(Fig. 1)
ENC004-1
• Always switch off the tool before installation or removal
of the battery cartridge.
• To remove the battery cartridge, pull out the set plate
on the tool and grasp both sides of the battery cartridge
while withdrawing it from the tool.
• To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Snap the set plate back into place. Be sure
to close the set plate fully before using the tool to
prevent the battery cartridge from accidentally falling
out of the tool.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Adjusting the depth of cut (Fig. 2)
Loosen the bolt (A) on the depth guide with the hex
wrench and move the base up or down. At the desired
depth of cut, secure the base by tightening the bolt (A).
Bevel cutting (Fig. 3)
Loosen the bolt (A) on the depth guide and the bolt (B) on
the bevel scale plate with the hex wrench. Set for the
desired angle (0° - 45°) by tilting accordingly, then tighten
the bolts (A) and (B) securely.
CAUTION:
• After adjusting depth of cut and bevel cutting angle, be
sure to tighten the bolts (A) and (B) securely.
Sighting (Fig. 4)
For straight cuts, align the "A" position on the front of the
base with your cutting line. For 45° bevel cuts, align the
"B" position with it.
NOTE:
• When making bevel cuts, view the cutting line on the
workpiece through the window in the blade case in
order to cut more accurately. If you have difficulty
seeing it because of the water tank, adjust the position
of the tank by tilting it backward slightly.
