RULES FOR SAFE OPERATION  
WHEN HAULING THE WORKSTAND IN A VEHICLE,  
securely tie it down to prevent movement and possible  
damage.  
Safe operation of this accessory requires that you read and  
understand this operator’s manual, the operator’s manual  
for the miter saw, and all labels affixed to the tool.  
NEVER put the workstand where operators or  
bystanders are forced to stand with any part of their  
body inline with the path of the saw blade.  
READ ALL INSTRUCTIONS  
KNOWYOURACCESSORY.Readtheoperator’smanual  
carefully. Learn the product’s applications and limitations  
as well as the specific potential hazards related to this  
product.  
NEVER STAND ON WORKSTAND. Serious injury could  
occur if the stand tips or you accidentally hit the cutting  
tool. Do not store any items above or near the stand  
where anyone might climb on the stand to reach them.  
MAXIMUM WEIGHT OF POWER TOOL MUST NOT  
EXCEED 100 POUNDS.  
MAXIMUM WEIGHT OF SAW AND WORKPIECE  
MUST NOT EXCEED 200 POUNDS.  
ALWAYS MOUNT MITER SAW so the workpiece is  
positioned in-line with the roller assemblies.  
CHECK TO MAKE SURE WORKSTAND DOES NOT  
KEEP THE WORK AREA CLEAN. Cluttered work areas  
and work benches invite accidents. DO NOT leave tools  
or pieces of wood on the saw while operating.  
ALWAYS WEAR SAFETY GLASSES WITH SIDE  
SHIELDS. Everyday eyeglasses have only impact-  
resistant lenses; they are NOT safety glasses.  
DO NOT USE THIS PRODUCT WITH OTHER  
EQUIPMENT or for other purposes.  
ALWAYS DISCONNECT THE SAW FROM THE POWER  
SUPPLY BEFORE ASSEMBLING THIS KIT. Make sure  
the switch is off when reconnecting the saw to a power  
supply.  
ROCK, SLIDE OR MOVE PRIOR TO USE.  
PUT THE WORKSTAND ON A FIRM LEVEL SURFACE  
where there is plenty of room to handle and properly  
support the workpiece.  
ALWAYS move mounted saw to the wheeled end of  
stand prior to transporting or taking down unit and  
ensure saw mounting brackets are securely locked.  
SAVE THESE INSTRUCTIONS. Refer to them frequently  
and use them to instruct other users. If you loan someone  
this product, also loan these instructions.  
BEFORE MAKING A CUT, BE SURE ALL  
ADJUSTMENTS ARE SECURE.  
ALWAYS GET HELP IF YOU NEED TO LIFT THE  
WORKSTAND. When lifting, hold the workstand close  
to your body. Bend your knees so you can lift with your  
legs, not your back.

to slide the saw mounting bracket assembly along  
the table edges or remove the bracket assembly  
from the table edges. If the saw mounting brackets  
will not fit over the edges, or if the brackets can  
be removed from the edges when the levers are  
locked, remove bracket assembly immediately  
and adjust bracket adjustment screw. See the

ASSEMBLY  
NOTE: Continue to hold the saw and bracket assembly  
with one hand until both levers are securely locked.  
MOUNTING THE MITER SAW TO THE  
WORKSTAND  
See Figures 13 - 14.  
Check position and adjust, if necessary, to make sure the  
weight of the saw is evenly balanced over the edges.  
Use the handles located at the rear of the saw mounting  
brackets to aid in installing or removing saw and bracket  
assembly.  
Ensure the saw is fully seated and locked in position, then  
securely tighten the four nuts holding the saw to the saw  
mounting brackets.  
Lift the saw and bracket assembly, allowing the assembly  
to tilt slightly toward your body.  
While still tilted toward you, hook the front clamp of the  
saw and bracket assembly onto the front edge of the  
table.  
WARNING:  
The saw mounting brackets are designed to fit  
snugly over the table edges with locking levers in  
the open position. With the locking levers in the  
lowered (locked) position, you should not be able  
to slide the saw mounting bracket assembly along  
the table edges or remove the bracket assembly  
from the table edges. If the saw mounting brackets  
will not fit over the edges, or if the brackets can  
be removed from the edges when the levers are  
locked, remove bracket assembly immediately  
and adjust bracket adjustment screw. See the  
Maintenance section of this manual. Failure to heed  
this warning may result in serious personal injury.  
WARNING:  
To avoid serious personal injury, make sure the  
curved front edge of the mounting brackets are  
securely seated over the front edge of table before  
seating the other end of the brackets. Failure to  
do so could cause you to lose control of the saw  
and bracket assembly, which could cause serious  
personal injury.  
Lower the saw and bracket assembly to allow the rear  
clamp of the bracket to seat fully over the rear table  
edge.  
Lock the brackets in position by lowering the locking  
levers.

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.  
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, dust, oil, grease, etc.  
WARNING:  
Do not at any time let brake fluids, gasoline,  
petroleum-based products, penetrating oils, etc.,  
come in contact with plastic parts. Chemicals can  
damage, weaken or destroy plastic which may  
result in serious personal injury.  
Periodically check all fasteners for tightness. Retighten as  
necessary.

WARNING:  
The saw mounting brackets are designed to fit  
snugly over the table edges with locking levers in  
the open position. With the locking levers in the  
lowered (locked) position, you should not be able  
to slide the saw mounting bracket assembly along  
the table edges or remove the bracket assembly  
from the table edges. If the saw mounting brackets  
will not fit over the edges, or if the brackets can  
be removed from the edges when the levers are  
locked, remove bracket assembly immediately and  
adjust bracket adjustment screw. Failure to heed  
this warning may result in serious personal injury.

SCREWDRIVER  
If the saw and bracket assembly can slide over the table  
edges or be removed from the table edges when the levers  
are locked, the bracket adjustment screws need to be  
tightened. If the saw and bracket assembly will not fit over  
both table edges, the bracket adjustment screw needs to  
be loosened.

NOTE: The saw should be removed from the mounting  
brackets before attempting to tighten or loosen the bracket  
adjustment screws.  
Fig. 23  
To adjust:  
Use a wrench to slightly loosen the nut.  
Turn the screw with a phillips screwdriver. Rotate  
clockwise if the bracket assembly needs to be tightened  
or counterclockwise if the assembly needs to be  
loosened.  
NOTE: If locking lever on saw mounting bracket cannot  
easily be pushed down into the closed position, the  
adjustment screw is too tight. Do not force locking lever  
into the closed position. Loosen the adjustment screw.  
Install the bracket on the front table edge then lower  
bracket to allow the rear clamp of the bracket to seat  
fully over the rear table edge.  
NOTE: The mounting bracket should fit snugly over the  
table edges when in the open position.  
When the correct position is achieved, wrench-tighten  
the nut to secure.  
Repeat with the second mounting bracket.
