WARNING:

Before performing any adjustment, make sure the tool is unplugged from the power supply. Failure to heed this warning could result in serious personal injury.

TO ADJUST THE LASER GUIDE

See Figure 42.

NOTE: Avoid direct eye exposure when using the laser guide.

Set both the bevel angle and the miter table at 0°.

Use the work clamp or a C-clamp to secure a piece of scrap wood.

Plug the saw into the power source and make a slight cut to score the wood.

Release the switch trigger and allow the saw blade to stop rotating before raising the blade.

Raise the saw arm and unplug the saw.

Loosen the blade bolt cover screw on the blade bolt cover until the cover can be raised.

Gently raise the lower blade guard bracket so that lower blade guard and blade bolt cover can be rotated up and back to expose the laser.

Rotate the blade by hand until you can push and hold the laser button and the laser is near the center of the workpiece as shown in figure 42.

MAINTENANCE

WARNING: WARNING:

When servicing, use only identical replacement parts. Use of any other part may create a hazard or cause product damage.

Do not at any time let brake fluids, gasoline, petro- leum-based products, penetrating oils, etc., come in contact with plastic parts. They contain chemi- cals that can damage, weaken or destroy plastic.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrica- tion is required.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc.

WARNING:

To ensure safety and reliability, all repairs should be performed by a qualified service technician at an authorized service center to avoid risk of personal injury.
