SQUARE CUTS
1. Accurately mark the line where the cut will be made on the beam. Install Beam
Rail (N) approximately 8" (200 mm) behind this line (The rack teeth on
beam rail should face away from line). Make sure beam is free of dirt, chips,
and other debris which would prevent magnets or beam rail from setting
flat and result in a crooked cut. Place Beam Rail (N) on the beam and
adjust, making sure it is parallel to the layout line (parallelism is most
important). Next install the two “C” Clamps (Z) to hold down end opposite
magnets.(Ref. Fig. 2)
2. Depress Clutch Knob (R) and slide BEAM BUG III onto beam rail.
NOTE: Clutch Knob (R) faces away from rack teeth on beam rail.
Be sure all four wheels are on the rail before starting. (Ref. Fig. 2)
OPERATING INSTRUCTIONS
3. In case Torchholder (H) was bumped during shipment, check to see
that it is parallel to the rail as follows (Ref. Fig. 3):
A. Lock Rackholder (I) on Rack (G) [or torchholder assembly].
B. Swing Torch (BB) to a horizontal position and measure distance
from Torch Tip (DD) to edge of Rack (N).
C. Swing Torch (BB) 180 0 and measure distance from Torch Tip
(DD) to edge of Rack (N) on other side.
D. These two measurements must be equal. If they are not, loosen
Socket Head Cap Screw (T) and nudge Torchholder (H) around
the vertical axis, and retighten Clamp Knob (U) when the mea-
sured distances (repeating Steps B and C) are equal.
