RIDGID 358 Instructions

Instructions For Nos. 358, 368 and 378 Tube Benders
Pre-Cut Tube To Correct
Length
1. Add all blueprint center to center dimen-
sions for the total tube length. Mark tube at
this total length. (Figure 1)
2. Because most blueprints are dimensioned
as though all corners were square, less
tube is actually required than the total of
the blueprint dimensions. Therefore,
REDUCE the total length by the number of
bends, using the Gain Scales on the
Swinging Arm. (See Figure 2)
3. Reduce the measured length of tube from
Step 1 by one graduation for each 90˚ bend
using the scale marked "90˚ Gain". Reduce
Length of tube by one graduation for each
45˚ bend using the scale marked "45˚ Gain".
(See Figure 2) Mark tube and cut.
