OPERATION
MACHINE MAINTENANCE
To keep machine in good working condition, simply
follow machine’s daily, weekly and monthly
maintenance procedures.
FOR SAFETY: When servicing machine, unplug
cord from wall outlet.
DAILY MAINTENANCE
(Every 4 Hours of Operation)
1. Empty and rinse out recovery tank thoroughly.
2. Remove float shut-off screen from recovery tank
and clean (Figure 15.)
3. When solution tank is empty, remove and clean
solution filter screen located at the end of the
hose inside the solution tank. When replacing, be
certain filter screen lies in the recessed pocket at
bottom of the tank. This will assure that all
solution in used from tank the next time the
machine is used.
4. Wipe off power cord and check for damage,
replace if necessary. Coil cord neatly after use.
5. Clean machine with an all purpose cleaner and
damp cloth.
6. Clean off any accumulated debris on the gearbox
shaft and inside the threaded portion of the hub
(Figure 16). An accumulation of debris around the
gearbox shaft, if not removed, may damage the
gearbox oil seal resulting in loss of oil in the
gearbox. If the gearbox is operated without oil,
severe damage may occur. (This requires
removing the cleaning head. To do this, refer to
“Repair Guide” section of this manual.)
7. Check the applicator jets in the head to ensure a
proper solution flow. A jet that sprays uneven or
that dribbles needs to be cleaned (Figure 17).
8. Twist the jet out. Turn it over. Blow out any
obstructions and reinstall the jet. Never use a
sharp solid object to dislodge an obstruction as
this will damage spray jet.
9. Rinse head assembly and cowling with fresh
water to remove debris.
FOR SAFETY: Lay machine on its right side when
cleaning. If it lies on the left side oil will grain out
of the gearbox.
10. Coat the motor shaft with lubricant before
reinstalling the cleaning head. Apply grease to
o-ring. Locate the head onto the shaft, making
sure the threads are aligned properly, and rotate
the head counterclockwise (Figure 18).
