MAINTENANCE AND INSPECTION

WARNING: To avoid serious accident, ensure the switch is in the OFF position and disconnect the plug from the receptacle during maintenance and inspection.

1.Inspecting the saw blade:

Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.

CAUTION:

If a dull saw blade is used, reactive force is increased during cutting operation. Avoid the use of the dull saw blade without repair.

2.Check the screws

Loose screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION: Using this power tool with loosened screws is extremely dangerous.

3.Inspecting the carbon brushes (Fig. 20)

The motor employs carbon brushes which are consumable parts. Replace the carbon brush with a new one when it becomes worn to its wear limit. Always keep carbon brushes clean and ensure that they slide freely within the brush holders.
