11. Observe the following cautions to avoid pressure
control damage.
CAUTION
To avoid damaging the pressure control, follow these
precautions.
Allow the main hose to act as a pulsation damp-
ener: Always use nylon spray hose at least 50 ft.
(15 m) long for the main gun; Never use a wire
braid hose; it is too rigid.
Never install a ball valve or shutoff device be-
tween the filter and the 50 ft. (15 m) hose.
Do not allow water or water-base material to
freeze in the pressure control.
CAUTION
Close the black fuel shutoff lever whenever you are
transporting the sprayer to prevent fuel from flooding
the engine.
Keep the sprayer upright and level when operating it
and transporting it. This prevents crankcase oil from
leaking into the combustion chamber, which makes
startup very difficult.
Setup
12. To use the wheel brake, lift the brake handle (A–
bottom rear of cart) to engage the brake. Lower
the handle to disengage the break. See Fig. 5. For
positive break engagement, be sure there is
proper tire pressure and that tire wear is not
excessive.
13. For how to operate and adjust the various features
of the LineLazer see pages 11–22.
14. Start the sprayer. See page 13.
