before installing or operating this sprayer.
Unpack the Llne Lazer. Carefully raise the handle

3. To install a second gun and hose, see page 12.
4. Fill the packlng nut/wet-cup (216) 1/3 full with
Graco Throat Seal Liquid (TSL), supplied, and keep
It filled, to help extend the pump life. See Fig 10-2.
5. Check the engine oll level. Refer to the Honda en-
mation: Remove one ofthe oil fill plugs; the oil should

be airnost overflowing. See Fig 10-2. Add oil as
necessary. Also readthe MAINTENANCE section on
page 23.
Recommended engine oil: Use a high-quality, deter-
gent oil, SAE IOW-40, classified “FOR
SERVICE SE or SF”.
6. Be sure your system Is properly grounded before
operating It. The grounding chain connected to the
tion. if you use the unit for stationary spraying, con-
cart must contact the ground at all times during opera-
nect the grounding clamp (1 59) to a true eaflh ground.
Read and follow FIRE OR EXPLOSION HAZARD on
page 5.
7. Fill the gas tank. See FUELING on page 11. I
8. Flush the pump to remove the lightweight oil which
was left in the pump to protect it from rust. Follow the
FLUSHING GUIDELINES on page
13.
9. Prepare the paint according to the manufacturer’s
recommendations. Remove any skin that may have
formed. Stir the paint to mix pigments.
Strain the paint through afine nylon mesh bag (avaii-

control damage.
CAUTION
TO avoid damaging the pressure control, follow
these precautions.
I. AIIOW the main hose to act as a pulsation
dampener:
a. Always
use nylon spray hose at least 50ft.
b. Never use a wire braid hose; it Is too rigid.
2. Never install a ball valve or shutoff device be-
tween the filter and the
50 ft. (15 m) hose.
3. Do not allow water or water-base material to

(15.2 m) long for the main gun.
CAUTION
Close the black fuel shutoff lever whenever you are
transporting the sprayer
to prevent fuel from flood-
ing
the engine.
Keep the sprayer upright and level when operating
it and wheniranspor\ing n. This prevents crankcase
oil from leaking into
the combustion chamber,
which makes startup very difficult

WARNING
Gasoline is extremely flammable and explosive un-
der certain conditions. To reduce the risk of a fire or
explosion:
1. Always shut off the engine before refueling.
2. Refuel in a well-ventilated area.
3. Do not smoke or ailow flames or sparks in the
area where
the engine is refueled or where the
gasoline is stored.
4. DO not overfill the tank. Make sure the filler cap
.is securely closed after refueling.
5. Fuel vapor or spilledfuel can ignite, If any fuel is
spilled during refueling, make sure the area is
dry before starting the engine.
1. Fuel specifications. Use automotive gasoline with a
pump octane number of
86 or higher. If the engine
fuel minimizes combustion chamber deposits.

use a higher octane fuel. Unleaded
2. Gasollnes containlng alcohol (gasohol). Do not
use gasohol which contains methanol, If the gasohol
does not contain cosolvenis and corrosion inhibitors

do not use the gasohol if it contains more than
5% methanol.
NOTE: The HONDA engine warranty does not cover

Installation
Relieve pressure. Install a SwitchTip

on the cylinder fits into the slots (H) at the base of the tip
guard (J). See Fig 16-1.
Place the seat (E) on a pencil, curved side out, as shown
in Fig

using the red or yellow gasket (C), be sure the flat side
faces out of the retainer (A). See Fig 16-1.
Screw the tip guard snugly onto the gun, holding it in the
desired position while tightening the retaining nut (A). '
NEVER use a wrench to turn the plastic tip guard (J), to
avoid damaging the guard.
