! CAUTION

Transporting, Placement & Mounting

To avoid injury always observe the ! WARNING following:

• Unplug electric cord. Before transporting the saw, rotate head and lock assembly to 60° right miter, lock into detent, and lock the head assembly in the lowered position.

Lifting Saw

•To avoid back injury, hold the tool close to your body when lifting. Bend your knees so you can lift with your legs, not your back.

•Lift by using the cast-in carry handles at each side of the bottom of the base.

•Alternate lifting method: When picking tool up from ground, use rear carrying handle and front carrying handle (above guard).

•Never lift tool by holding main switch handle. This may cause serious damage.

•Never carry the miter saw by the power cord or the operational handle. Attempting to lift or carry the tool by the power cord will damage the insulation and the wire connections resulting in electric shock or fire.

•Observe the position of the saw. People standing behind it could be injured by thrown debris.

•Place the saw on a firm, level surface where there is plenty of room for handling and properly support- ing the workpiece.

•Bolt, nail or clamp the saw to its support.

Be careful not to over-drive nail or over-torque the bolt. This could

crack foot or damage base.

Mounting Applications

Mounting to Workbench

Mount the saw using either the four bolt holes (5/16") or the four nail holes to the workbench. Check for clearance to the left and right of the saw.

1. Each of the four mounting holes should be bolted securely using 5/16" bolts, lock washers, and hex nuts (not included).

2. Locate and mark where the saw is to be mounted.

3.Drill four (4) 5/16" diameter holes through work- bench.

4. Place the miter saw on the workbench aligning holes in base with holes drilled in workbench. Install bolts, lock washers and hex nuts. As an alternative, you can mount the saw using drywall screws in the four nail holes.

Supporting surface where saw is to be mounted should be examined carefully after mounting to ensure that no movement can occur during use. If any tipping or walking is noted, secure the work- bench or stand before operating the compound miter saw.
