ASSEMBLY

CAUTION:

Always  be  sure  that  the  tool  is  switched  off  and  unplugged  before

carrying out any work on the tool.

Removing or installing saw blade

CAUTION:

Do  not  use  saw  blades  which  do  not  comply  with  the  characteristics

specified in these instructions.

Be  sure  the  blade  is  installed  with  teeth  pointing  up  at  the  front  of  the

tool.

Use only the Makita wrench to install or remove the blade.

Never depress the shaft lock while the saw is running.

To remove the blade, press the shaft lock fully so that the blade cannot revolve

and use the hex wrench to loosen the hex bolt counterclockwise. Then remove

the hex bolt, outer flange and blade.
To  install  the  blade,  follow  the  removal  procedure  in  reverse.  BE  SURE  TO

TIGHTEN THE HEX BOLT CLOCKWISE SECURELY.
When changing blade, make sure to also clean upper and lower blade guards

of  accumulated  sawdust.  Such  efforts  do  not,  however,  replace  the  need  to

check lower guard operation before each use.

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.

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 blade. Set the base on the workpiece to be cut without the blade

making any contact. Then turn the tool on and wait until the 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 properly follow your intended cut line, do not attempt

to turn or force the tool back to the cut line. Doing so may bind the blade and

lead to dangerous kickback and possible serious injury. Release switch, wait

for 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.
