MAINTENANCE
1
Check the packing nut/wet–cup daily. Relieve the
pressure. Keep the packing nut/wet–cup 1/3 full with
TSL at all times to help prevent fluid buildup on the
piston rod and premature wear of packings. Tighten
the packing nut just enough to stop leakage. Over-
tightening may cause binding and excessive packing
wear. Use a 1/4 inch diameter rod to adjust the nut.
2
Clean the fluid filter often and whenever the spray-
er is stored. First relieve pressure. See manual
307–273 for the cleaning procedure.
3
For very short shutoff periods, leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
4
At the end of each work day , flush the sprayer
and relieve pressure. Leave the pump and hoses
filled with mineral spirits to help prevent pump corro-
sion and freezing. See
FLUSHING GUIDELINES,
page 10.

5
If the pump stalls at the top of its stroke, relieve
fluid pressure, remove the plug from the top of the hy-
draulic motor, and push the spool all the way down.
See Fig 7. Replace the plug and restart the sprayer.
NOTE: Relieving pressure whenever you are not using
the sprayer helps prevent the pump stalling at
the top of its stroke.
6
Coil the hose and hang it on the hose rack when
storing it, even for overnight, to help protect the hose
from kinking, abrasion, coupling damage, etc.
7
Check the hydraulic fluid level occasionally. Add
fluid as necessary to keep the fluid level between the
ADD and FULL marks on the dipstick. See page 9.
8
Change the hydraulic fluid every 2000 hours of op-
eration or 12 months, whichever comes first. Also
clean the hydraulic pump intake filter and replace the
disposable filter in the return line. First, relieve pres-
sure. then remove the sprayer shield. Refer to
Re-
placing the Electric Motor on page 17 to get at the
filters. Remove the old hydraulic fluid and clean the
sump.
9
Periodically, or if the electric motor is overheating,
unplug the sprayer , relieve pressure, remove the
shield, and clean all paint and dirt from the shield, fan
blades, motor and cooling fins.
10 To transport the sprayer , empty the wet-cup, or re-
duce the level of Throat Seal Liquid to 1/3 full or less
and stuff a rag into the wet-cup. Load the sprayer as
shown in Fig 8. To avoid leakage of hydraulic fluid,
never lay the sprayer on its side.
