How to Operate a Double End Trim Saw:
Before operating the machine, please read the “Safety Instructions to the Operator” on Page No. 8. Other important
information and features need to be learned before operating the machine.
Rotation:
The blade must rotate to the rear of the machine on the underside of the blade.
Blade Guard:
Model DM200R : The blade and belt drive are enclosed. When the saw arms are lowered, the lower blade guard rotates
up into the main blade guard. The blade continues through the work as the lower blade guard rotates up via the linkage arm.
Model DM400 : When the saw arms are lowered, the Blade Guard Bearing, P/N 2B2P05 contacts Blade Guard Guide, P/
N 4BM68. The blade continues through the work as the blade guard rides forward on the guide. ALWAYS keep Blade
Guard Guide as close to the material as possible for maximum protection of the operator.
These machines are general purpose in their design. Therefore, the USER should attach any additional guarding to
the blade guard or table base if the cutting application causes unsafe blade exposure.
Positioning the Work and Alignment of Fences :
Fences should be set so that the centerline of the work is either to the front, or on the centerline of the blade. Fences must be
adjusted so that short pieces cannot be trapped between the blade and the fences. Fences must be in line with each other—
front to back (see Diagram “B“). If fences are set 5/8’ in front of the centerline, then when changing mitre angle, the length
dimension at 45 and 90 degrees will stay the same. No adjustment to measuring scale will be necessary. However, any other
angles require slight adjustment of the scale. Note: The scrap drop off piece needs to be backed up by the rear outside
fence. If the trimmed cut-off material is not supported by the rear outside fence, the cut-off piece can catch on the blade with
the possibility of firing the scrap piece into the blade. This will cause damage to the blade, the blade guard, and has the
potential for harming the operator. Always back up the cut-off trim piece with the outside fence supplied.
Measuring Scale and Pointer for Length:
The length measuring scale (used to determine length of cut between two saw heads) is located on top of precision
gear rack. The measurement rule and bar must be reset if the fences are moved or the blades are changed. If a small
adjustment is needed, this can be accomplished by adjusting the pointer located on the right saw head carriage or
base. The measurement rule and bar can be reset by loosening screws that hold it in place on top of gear rack. Move
the bar with tape, left or right as necessary, to correct length dimension between the two blades.
To Move Saw Head Base:
1. Loosen hand knob located in front of saw head base.
2. Rotate crank handle until pointer registers desired dimension. Always move saw head base in one
direction to eliminate any backlash between gear rack and pinion.
3. Tighten hand knob. This automatically squares up saw head base to the front rail or tube.
