Maintenance; Operation - Makita HS7611 Instruction Manual

Hex wrench storage
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
► Fig.20: 1. Hex wrench
Connecting a vacuum cleaner
Optional accessory
When you wish to perform clean cutting operation,
connect a Makita vacuum cleaner to your tool using the
dust nozzle.
1. If your circular saw has a long lever (country spe-
cific), replace it with the short lever supplied with the
dust nozzle.
► Fig.21: 1. Long lever (country specific) 2. Screw
3. Short lever
Do not use the dust nozzle with the long lever attached.
You will not be able to make a cut because the lower
guard movement is hindered by the dust nozzle.
2. Install the dust nozzle on the tool using the screw.

3. Connect a hose of the vacuum cleaner to the dust
nozzle.

OPERATION

CAUTION:
Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
will result in overheating the motor and dangerous
kickback, possibly causing severe injury.
CAUTION:
Always use a front grip and rear
handle and firmly hold the tool by both front grip
and rear handle during operations.
► Fig.24
Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool.
If both hands are holding saw, they cannot be cut by
the circular saw blade. Set the base on the workpiece
to be cut without the circular saw blade making any
contact. Then turn the tool on and wait until the circular
saw blade attains full speed. Now simply move the tool
forward over the workpiece surface, keeping it flat and
advancing smoothly until the sawing is completed.
To get clean cuts, keep your sawing line straight and
your speed of advance uniform. If the cut fails to prop-
erly follow your intended cut line, do not attempt to turn
or force the tool back to the cut line. Doing so may bind
the circular saw blade and lead to dangerous kickback
and possible serious injury. Release switch, wait for cir-
cular saw blade to stop and then withdraw tool. Realign
tool on new cut line, and start cut again. Attempt to
avoid positioning which exposes operator to chips and
wood dust being ejected from saw. Use eye protection
to help avoid injury.
Rip fence (Guide rule)
Optional accessory
► Fig.25: 1. Rip fence (Guide rule) 2. Clamping screw
The handy rip fence allows you to do extra-accurate
straight cuts. Simply slide the rip fence up snugly
against the side of the workpiece and secure it in posi-
tion with the clamping screw on the front of the base. It
also makes repeated cuts of uniform width possible.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
CAUTION:
Clean out the guard to ensure
there is no accumulated sawdust and chips
which may impede the operation of the guarding
system. A dirty guarding system may limit the proper
operation which could result in serious personal
injury. The most effective way to accomplish this
cleaning is with compressed air. If the dust is being
blown out of the guard, be sure the proper eye
and breathing protection is used.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Adjusting the parallelism
This adjustment has been made at the factory. But if it is
off, you can adjust it as the following procedure.
1.
Make sure all levers and screws are tightened.
Slightly loosen the screw illustrated.
► Fig.26: 1. Screw 2. Base
2. While opening the lower guard, move the rear of
the base so that the distance A and B becomes equal.
3. Tighten the screws and make a test cut to check
the parallelism.
Adjusting 0°-cut accuracy
This adjustment has been made at the factory. But if it is
off, you can adjust it as the following procedure.
1. Slightly loosen the clamping screws on the front
and rear of the tool.
2.
Make the base perpendicular to the blade using
a triangular rule or square rule by turning the adjusting
screw.

3. Tighten the clamping screws and then make a test
cut to check the verticalness.
