Maintenance
Solution Pump Drive Belts
To tighten the solution pump belt:
1. Loosen the bolts which hold the solution pump
mount to base.
2. Adjust the position of the belt tension adjusting bolt
until the proper belt tension is achieved. (1/2"
deflection in the center of the belt, halfway
between the pulleys).
3. While checking the alignment, tighten the nuts
which hold the solution pump mount to base.
4. Check belt and pulley every 100 hrs.
Float Valve (Water Box)
1. Check the float valve weekly for proper operation.
If overfilling is a problem, check the plunger for a
proper seal. Replace tip on plunger if needed.
NOTE: If the float ball has any water inside it must be
replaced.
When replacing float ball, DO NOT over- tighten, as
the rod can puncture the ball. Make sure to tighten
the nuts on the rod.
2. Disassemble the valve and check the piston and
seat for damage, replace if needed. See the “Illus-
trated Parts Listing” for a parts break-down.
Waste Tank Float Valve
The float valve in the waste tank shuts the unit down
once the waste tank becomes full. Debris can collect
around the hinge of the float valve. Check the float
valve for debris at least once a month.
Waste Tank Strainer Basket
The strainer basket located inside the waste tank
should be removed and cleaned whenever it is full of
debris. This should be done on at the end of each job.
Waste Tank Vacuum Inlet Filter
The Vacuum Inlet Filter located inside the waste tank
should be removed, cleaned and inspected at the
beginning of each day. When replacing in tank ensure
that flow indicating arrow is pointing down.
Solution Screen (Outlet)
Inspect the solution screen after the first week of
running the unit by unscrewing the screen and remove
any accumulated debris. Inspect the screen again at 2
and 4 weeks.
The solution screen should then be inspected every
month. However, if the screen has a frequent build-up
of debris it should be inspected and cleaned more
often.
