Paint Cleaning Solutions
Some cleaning solutions and solvents used in high pressure
washers may bleach the finish if used in high concentration
or not rinsed from the machine. This can be avoided by
diluting the cleaning solution or not letting it set too long.
Fasteners (Nuts and Bolts)
It is particularly important to check all nuts and bolts for
tightness after the first 5 hours of use. All drive train bolts
should receive extra attention. Thereafter, check every
250 hours.
If a particular difficulty is experienced, check the symptoms
listed below. Possible causes and remedies are given for
each symptom. If the trouble is not corrected after
following the suggested solution, call your dealer or call
Terramite Corporation.
Total Failure of Hydraulic Power
(Engine is running, but nothing works)
Stripped engine to transmission coupling. Must be replaced.
Loss of Tram Power
The hubs may be disengaged for towing. This will cause
loss of tram power.
This may indicate a worn transmission. Check with factory
technician
Loss of Sweeping Power
Check for:
1. Low hydraulic oil.
2. Collapsed hose (hose can collapse internally, not
showing any visible signs.)
3. Worn Pump. Check pump pressure.
4. Internal Valve leakage. Valves will sometimes
develope leaks between the spools, yet not leak
outside. Switching hoses to another valve will
determine whether the valve section is bad.
5. Broken or weak relief valve. Check pressure. Check
for fatigued or broken relief valve spring. All
cylinders will lack power. You will have a little more
power when your machine is cold. A weakened
spring will lose power so gradually that you may not
notice the decline in power until it seriously affects
the machine performance. A broken spring will cause
a sudden drop in cylinder power.
Trouble Shooting
Sluggish and Slow Operation
Oil still cold. Pump badly worn or damaged. Restriction
in suction line. Clogged oil filter or sump strainer.
Control Valve Sticks or Works Hard
Normally, this is a problem for your dealer's service
department. It is usually dirty valves, tie bolts too tight or
float detent position adjusted too tight.
Street Sweeper Doesn't Move in Either
Direction
If this happened over a period of time, the transmission is
totally worn out. If it happened instantly, check for the
following:
1. Make sure rear lock-outs are in.
2. Foot pedal disconnected.
3. Bolts broken on coupling.
Transmission/Pump Makes Noise
First check the oil viscosity. If too high, replace with
specified oil. Then look for a kink or dent in oil lines. If
not of these, it may be air in the system. See your dealer.
Erratic Motion
1. Retract all rods and check hydraulic oil level.
2. Broken or weak pedal spring.
3. Worn transmission.
Hydraulic Oil Foams
1. Low oil supply.
2. Air leak in line from reservoir to pump.
3. Incorrect hydraulic oil.
4. Blocked valve restrictor.
5. Check sump hose for tightness.
