28.STOP OPERATION IMMEDIATELY IF ANY ABNORMALITY IS DETECTED. Should the power tool be detected as out of order or should other abnormalities be observed during operation, stop using the power tool immediately.

29.NEVER LEAVE THE POWER TOOL RUNNING UNATTENDED. TURN POWER OFF. Don’t leave the power tool until it comes to a complete stop.

30.CAREFULLY HANDLE THE POWER TOOL. Should the power tool be dropped or struck against hard materials inadvertently, it may be deformed, cracked, or damaged.

31.DO NOT WIPE PLASTIC PARTS WITH SOLVENT. Solvents such as gasoline, thinner, benzine, carbon tetrachloride, and alcohol damage and crack plastic parts. Do not wipe them with such solvents. Wipe plastic parts with a soft cloth lightly dampened with soapy water.

32.WHEN REPLACING A COMPONENT PART, ADOPT THE SAME TYPE. When replacing a component part with a new one, adopt the same type of new part. Also, never attempt to repair the power tool yourself. Bring it to an authorized service center for repair.

SERVICE AND REPAIRS

All quality tools will eventually require servicing or replacement of parts due to wear from normal use. These operations should ONLY be performed by an AUTHORIZED SERVICE CENTER.

REPLACEMENT PARTS

When servicing use only identical replacement parts.

POLARIZED PLUGS

To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other).

This plug will fit in a polarized outlet only one way.

If the plug does not fit fully in the outlet, reverse the plug.

If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.

EXTENSION CORD

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current the power tool will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table below shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
