Read and understand all ins t r u c tions. F a ilure to

follow all instructions listed below and in your miter saw manual m ay result in serious personal injury.

Ful l y ass e m b l e an d ti g h t e n al l th e fasteners required for this stand. Also rem e m ber t o o c c asiona l l y c h e ck t h e stand and make sure it is still tight. A

loose stand is unstable and may shift in use and cause serious injury.

Turn tool switch off and disconnect power before mounting to the stand. Unintended

startup during assembly can cause injury.

Before operating make sure the entire unit is placed on a solid, flat, level surface.

Serious injury could occur if tool with stand is unstable and tips.

Never stand on tool or its stand or use as ladder or scaffolding. Serious injury could

occur if the tool is tipped or the cutting tool is acc i d e n tally con t a c t ed. Do not store materials on or near the tool such that it is necessary to stand on the tool or its stand to reach them.

Use only Bosch replacement parts. Any others may create a hazard.

The Miter Saw should be firmly mounted to the stand per the instruction manual.

After mounting the Miter Saw to the stand, align, position and balance the Miter Saw per the instruction manual.

Before use, verify that all stand parts are free from damage and/or deformity.

Bef o r e u se, veri f y t h at all pa r t s o r com p o n e nts of the stand are prope r l y installed.

Before use, swing open each of the legs until the pin clicks, locking the legs in position.

When mounting the Miter Saw to the stand, make sure that the tool lock knobs are in the “u nlo ck” position, so the t ool mo unt w ill engage with the main rail. Be sure to hold the saw until it is s ecured to prevent it from falling off the rails. Mounting bracket locking knobs should then be tightened.

Wh en remo vin g t he Mite r S aw fro m t he stand, rotate the tool mount lock knobs until they are in the “unlock” position. Hold the Miter Saw firmly to prevent the saw from falling off the rails. Carefully remove the Miter Saw.

Do not modify the stand in any manner or use the stand for any purpose other than is stated in these instructions.

Because cut material may cause the stand to become unb al anced, always be sure the material is supported properly. Also, if the piece being cut is placed far beyond the work support, stand legs on the opposite side may sud d e n l y be li f t e d up due t o w eight imbalance. To prevent this from occurring, hold the opposite side firmly before cutting.
