Maintaining the PowrHandler

Perform the following steps to keep the PowrHandler drive
system running smoothly.
1. Check the level of the hydraulic oil in the hydraulic tank
daily. If necessary, fill the hydraulic tank with hydraulic
fluid (P/N 0349909) until it reaches the proper operating
level.
2. Check all hoses for excessive wear, abrasions, and weak
spots regularly. Replace, if necessary.
3. Check all fittings for leaks regularly. Tighten, repair, or
replace as needed.
4. Check all nuts and bolts for tightness regularly. Tighten, if
necessary.
5. Check the air pressure in the rear tires.

Maintaining the Filter Assembly

Clean the filter regularly. Dirty or clogged filters can greatly
reduce filtering ability and cause a number of system problems
including poor spray patterns, clogged spray tips, etc.
Cleaning
To clean the filter, perform the following procedure.
1. Follow the "Pressure Relief
Procedure" found in the Operation
section of this manual.
2. Remove the filter cap assembly and
spring.
3. Pull the filter element with ball
straight out of the filter body.
4. Clean inside the filter body, filter
element with ball, and filter cap
assembly using the appropriate
solvent.
Use care in handling parts as
i
dirt, debris, scratches, or nicks
may prevent o-rings or gaskets
from sealing.
This filter element filters from
i
the inside out. Be sure to
clean the filter element
thoroughly on the inside. Soak
in solvent to loosen hardened
paint or replace.
Inspection
Inspect all parts of the filter assembly before reassembly.
1. Inspect the ball inside the filter element. If the ball has
pressure cuts or scratches, replace the filter element.
a. If the ball is cut, remove the Teflon o-ring using an o-ring
pick and remove the carbide seat.
b. Check the seat for nicks or grooves. If the seat is
damaged, replace.
i
Removal of the Teflon o-ring will damage the o-ring
and require replacement.
2. Remove the spring from the spring guide on the filter cap.
a. Measure the length of the spring uncompressed. If
it measures less the 1.9 cm (3/4") from end to end,
replace.
b. Push the spring back onto the spring guide until it
"snaps" back into position.
3. Inspect the two Teflon gaskets and the Teflon o-ring for
deformity, nicks, or cuts. Replace, if needed.
i
The Teflon gaskets, Teflon o-ring, and spring are
packaged in Filter Service Kit P/N 0349700.

Reassembly
After cleaning and inspecting all parts, reassemble the filter.

1. Place the carbide seat into the filter body. Make sure the
beveled side of the seat is facing up.
2. Place the Teflon o-ring into the groove on the outer
diameter of the carbide seat.
3. Place the filter element with ball into the filter body.
i
The top and bottom of the filter element with ball
are identical.
4. Push the spring back onto the spring guide of the filter cap
until it "snaps" back into position, if not already done.
5. Place the thin Teflon gasket onto the step at the top of the
filter body.
6. Place the thick Teflon gasket onto the top of the thin
gasket.
7. Tighten the filter cap assembly onto the filter body
Use of Wagner-approved hydraulic fluid (P/N
0349909) is mandatory in the hydraulic system.
Do not use any other hydraulic fluid. Use of any
other hydraulic fluid may seriously damage the
Attention
hydraulic system and will void the warranty.
1. Check the hydraulic fluid daily. It should be at the "Full"
mark on the dipstick. If it is low, add only Wagner-
approved hydraulic fluid (P/N 0555425). Never add or
change hydraulic fluid except in a clean, dust-free area.
Contamination of the hydraulic fluid will shorten hydraulic
pump life and may void warranty.

2. Change the hydraulic fluid every twelve months. Drain
the old fluid from the tank and fill with 4 quarts of hydraulic
fluid. Start the sprayer at just enough pressure to operate
the fluid section. Run the sprayer at this low pressure
for at least 5 minutes. This removes air from the system.
Check the fluid level after this procedure. Do not over-fill.
When replacing the hydraulic filter during a fluid
i
change, it may be necessary to add up to one
additional quart of hydraulic fluid.
3. The hydraulic system has an external, replaceable
hydraulic filter. Change the filter every twelve months.
4. The hydraulic pump should not be serviced in the field.
If service on the hydraulic pump is required, it must be
returned to Wagner.
