Maintenance - Graco EM 5000 Instructions-Parts List Manual

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 6.
1. Check the packing nut/wet–cup (C) daily. Relieve
the pressure Keep packing nut/wet–cup1/3 full of
TSL at all times to help prevent dried fluid from col-
lecting on the piston rod, and to reduce premature
wear of the packings. The packing nut/wet–cup
should be tight enough to stop leakage, but no tight-
er. Over–tightening the packing nut/wet–cup may
cause binding and excessive packing wear. Use a
metal punch and a light hammer to adjust the nut.
See Fig. 7.
2. Clean the fluid filter (B) often and whenever the
sprayer is stored. Relieve the pressure. Refer to
manual 307–273, supplied, for the cleaning proce-
dure of the filter.
3. Flush the sprayer at the end of each work day and
fill it with mineral spirits to help prevent corrosion and
freezing of the pump. See FLUSHING on page 11.
CAUTION
To prevent pump corrosion, and to prevent fluid from
freezing in the pump and pressure control, never
leave water or any paint in the sprayer. If water or
paint freezes in the pressure control, it may prevent
the sprayer from being started, cause loss of pres-
sure or stalling, and cause serious damage to the
pressure control. Always use mineral spirits for the
final flush and relieve the pressure. Leave the
mineral spirits in the sprayer.
4. For very short shutoff periods, leave the suction
tube in the paint. Relieve the pressure. Clean the
spray tip.
5. Coil the hose and hang it on the hose rack (A) when
storing it, even for overnight. Proper storage of the
hose helps protect it from kinks, abrasion, coupling
damage.
