Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol
1. Engage trigger lock.
2. Close the bleed-type master air valve.
3. Disengage the trigger lock.
4. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun to
relieve pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system,
having a waste container ready to catch
drainage. Leave drain valve(s) open until
you are ready to spray again.
7. If you suspect the spray tip or hose is
clogged or that pressure has not been
fully relieved:
a. VERY SLOWLY loosen tip guard
retaining nut or hose end coupling to
relieve pressure gradually.
b. Loosen nut or coupling completely.
c. Clear hose or tip obstruction.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the
Pressure Relief Procedure when you stop spraying
and before cleaning, checking, or servicing the
equipment.

Trigger Cable
Disengage the cable
1 Grasp cable (402) behind block (A).
2 Pull cable back 1/2 in. (13mm) and then out of
the block.
Engage the cable
1 Slide the cable (402) into block (A).
2 Seat end of the cable jacket firmly in the seat of the block.
The gun is remotely triggered with the dual gun
selector on the handle bar. To reduce the risk of
injection due to remotely triggering the gun by
accident, always disengage the trigger cable from
the block before handling the gun. Before you
remove the gun from the holder, engage the gun’s
trigger safety latch.
NOTICE
To ensure the trigger cable functions properly, keep
the seat in the trigger cable block (A) and the end of
the cable jacket clean at all times.

Second Gun Kit Installation
NOTE: Fig. 2, which shows the second gun
(outside gun) being mounted on the pump
side of the cart, represents the installation at
step 3.
NOTE: If you want to switch the gun
assemblies to the other side of the unit at this
time, see To Mount the guns on engine-
side of cart, page 7 before installing the
second gun kit.
1 Disengage the cable (402) from block
(A) of the unit’s existing gun. See Fig. 1.
Engage the trigger safety.
2 Loosen the carriage clamps (D). Slide
the carriage bar (B) off the cart.
3To mount gun bar on pump side,
slide clamp (405) onto carriage bar (B)
as shown in Fig. 2. Slide the carriage
bar through the pump-side carriage
clamp (D) and into the center of the
cart. Slide another clamp (405) onto the
carriage bar.
To mount gun bar on engine side,
follow step 3, expect slide the carriage
bar through engine-side carriage clamp
(D) and into the center of the cart. Make
sure knobs of the clamps (405) face back
toward handle bars.
4 Slide carriage bar (B) through opposite
carriage clamp. Tighten carriage
clamps (D).
5 Slide second gun bar (404) far enough
into carriage bar so that clamp (405)
engages the bar. Position clamps (405)
over the notches in carriage bar (B) and
tighten clamps.
NOTE: For stable gun operation, the second
gun bar (404) has a maximum recommended
extension from the carriage bar of about
11-1/4” (286 mm).
6 Disconnect trigger cable from second
gun at screw (34). See Fig. 2, Detail B.
7 Unscrew the filter’s second outlet cap
(J). Screw hose (403) onto filter nipple.
8 Remove guide clamp screw from the
area (F).
9 Snap cable brushing (H) into fluid plate
(G). Route trigger cable (402) parallel
with the main gun cable, separating the
guide clamp (F) to feed the cable
through. Install and tighten the guide
clamp screw (F). Route the cable
through the cable guide (K) and to the
second gun.
10 Slide the hooked end of cable (402)
through hole (M) in the lever plate (L).
Rotate the hook and slide it back until it
hooks on the plate. See Fig. 2, Detail A.
11 Reconnect trigger cable to the second
at screw (34). Torque screw to 15 in-lb
(1.7 N·m), then back it off 1/6 to 1/8 turn
and tighten jam nut (99) while holding
screw (34). Be sure plate (94) moves
freely.
12 Install clip (401) to hold the cable onto
the frame.
13 Connect both trigger cables to the
blocks (A). See Fig. 2. Adjust cable
tension. See page 9.
14 Do not install the spray tip until the
system is primed. See your complete
LineLazer manual for the startup
procedure.

Adjust Simultaneous Gun Triggering
1. Align the front of guns by adjusting the
gun arms. See page 7.
2. Position the dual gun selector to trigger
both guns. See page 9.
3. Start the sprayer, using water, or spray
on cardboard. Trigger the guns to see if
the lines begin at the same time and
place.
If one gun triggers before the other, reduce
the cable tensions of the gun that triggers
first. See Trigger cable tension adjustment
on page 9.
If one line starts in front of the other, adjust the
position of the guns. See page 7.
Re-trigger the guns to check adjustments.
Positioning Gun Arm Assembly
When the guns are moved: 1. Disengage the cables (402, H) first. See
page 3. Pull out more of the 50 ft. (15 m)
hose, if necessary.
2. After moving the guns, reposition the tip
guard so it is parallel to the ground and
its “wings” face the front and back of the
unit.
To reduce the risk of fluid injection injury, always
disengage the trigger cable to the gun(s) before
moving or adjusting the guns or gun arms. See
page 3.
NOTICE
Do not kink the cables, which could prevent
them from properly triggering and
untriggering the guns.

3. Disengage the gun trigger safety latch
and engage the cable (402, H).
Vertical position of first or second gun:
1. Loosen the post/arm clamp (6) and
move the gun up or down.
2. Engage the trigger cable.Horizontal
position of second gun:
Method 1:
1. Disengage the cable (402). Loosen the
clamps (405).
2. Slide the second gun bar (404)
horizontally as desired, but be sure both
small clamps engage the second gun
bar.
3. Tighten the clamps and engage cable
(402).
Method 2:
1. Disengage the cable (402). Loosen the
post/arm clamp (6) and rotate gun out to
the side.
2. Tighten the bolt and engage cable (402).
NOTE: Use methods 1 and 2 together to
obtain the maximum distance of 33-1/2” (851
mm) between the center of two guns.
To mount guns on engine-side of the cart:
1. For both guns, disengage the cables
(402, H) and engage the trigger safety
lever. See Fig. 4.
2. Loosen gun holder knobs (93) and
remove the guns. Lay guns out of the
way.
3. Remove knobs (G) on both carriage
clamps (D). The carriage bar (B) and
extension clamps (F) will drop down.
4. Lift the front tire and rotate the carriage
180° under the cart and to the other side
of the cart.
5. Position the carriage bar below the
carriage clamps (D). Align the holes in
the top of the extensions clamps (F) with
the holes in the carriage bar clamps and
install the knobs (G). See Fig. 3, Detail A.
6. Loosen the post/arm clamps (6) and
rotate the gun arms (G) forward. Tighten
the clamps.
7. Install the guns. See page 8. Note to
which gun and position on the dual gun
selector each of the cables (402, H)
goes.
8. Route the hoses and cables carefully to
prevent kinking. Position the tip guards
and engage the cables (402, H).

Trigger Cable and Dual Gun Selector Operation
In a two-gun operation, the second gun cable
(402) is black with a light-red cover at each
end. Trigger from the pump side (or outside)
position of the dual gun selector (L).
To trigger one gun, move the selector (L) left
or right, depending on how your cables are
routed to the guns, until the spool (M)
protrudes through the plate. You may need to
move the plate (N) a little to get the spool
through.
To trigger both guns, center the selector (L)
Trigger cable tension adjustment
(Fig. 6)
1 Relieve pressure, page 2.
2 Be sure the gun is properly mounted in
holder as instructed in Step 4 under
Mount Gun in the Gun Holder, page
8.
3 Pull the actuator level (94) forward and
hold it. Lift up on the gun trigger (T) until
there is slight resistance. Visually check
to see if there is about 1/32 to 1/16 in/
(1-2 mm) gap between the trigger lever
(H) and where the gun trigger touches
the bar.
4 To adjust the tensions, loosen the
screw in the block (P). Slide the block
forward to increase the gap and
backwards to decrease the gap.
Tighten the screw.
5 Recheck the gap and continue
adjusting as needed.
NOTICE
Always note to which gun and position on
the dual gun selector (L) each of the cables
goes so the correct gun is triggered.
NOTICE
A loose cable prevents the gun from being
fully triggered, which causes premature
wear of the gun needle. A tight cable
prevents the gun from being fully
untriggered, which results in dripping and
premature tip wear. Follow steps at the
right if adjustment is needed.
NOTICE
To prevent premature wear of the cable, do
not allow the cable (402) to rub against the
outside edges of the slot (S) in the block
(A). Rotate the block slightly to eliminate
rubbing.
