NOTE: Fig. 7 represents the installation at Step 3.
NOTE: To switch the gun assemblies to the engine side
of the cart, refer to the instructions on page 17 before in-
stalling the second gun kit.
1. Disengage the trigger cable from the block (48) of
the unit's existing gun. See page 21. Engage the
gun's trigger safety latch.
2. Loosen the carriage clamps (B, C). Slide the
carriage bar (4) off the cart.
3. For mounting the second gun bar on the pump
side of the cart: Slide a clamp (405A) onto the
carriage bar (4). Slide the carriage bar through the
pump-side carriage clamp (B) and into the center
of the cart. Now slide another clamp (405B) onto
the carriage bar. See Fig. 7.
For mounting the second gun bar on the engine side
of the cart: Follow Step 3, except slide the carriage
bar through the engine-side carriage clamp (C) and
the into the center of the cart. The knobs of the
clamps (405A, 405B) must face back toward the
handle bars.
4. Slide the carriage bar (4) through to the opposite car-
riage clamp. Tighten the carriage clamps (B,C).
5. Slide the second gun bar (404) far enough into the
carriage bar that the clamp (405B) engages the bar.
Position the clamps (405A, 405B) over the notches
(A) in the carriage bar (4) and tighten the clamps.

hole (F) in the lever plate (122). Rotate and slide the
hook back until it engages the plate. See DETAIL A.

screw (34). Torque the screw to 15 in–lb (1.7 N.m),
back it off 1/16 to 1/8 turn and then tighten the jam
nut (99) while holding the screw (34). Be sure the
plate (94) moves freely.
