Optimum Performance
IMPORTANT : The optimum performances of
the debris blower are only achieved after 10 to
15 minutes of debris blower operation. It is
therefore important to ensure that the hydraulic
oil reaches a temperature of over 40ºC (104ºF)
before judging the debris blower performances.
The following chart serves as a guide in case
of a malfunction. If the problem is not solved
after taking the appropriate corrective
measure, contact your dealer.
WARNING: Several corrective measures
present a certain risk, which may cause serious
injuries or death.
Only a qualified person, familiar with the risks
associated with hydraulics, electricity and machinery
should perform the repairs. Review the safety
precautions at the beginning of this manual
.
WARNING: Hot engine parts and hydraulic oil
can cause serious burns. Always let the engine
cool before proceeding with repairs or
maintenance.
CAUTION: The oil temperature must never go
above 65ºC (149ºF) to avoid damages to the
hydraulic components.
PROBLEM CORRECTIVE MEASURE
1. The Impeller does
not turn
•
Check if an object is blocking the impeller
•
Check that the PTO is engaged
•
Check for oil leaks
•
Check if the pump is in recirculation mode
•
Check hydraulic pump oil level and add some if needed
•
Check that the input and output hoses are connected
•
Check that the input and output hoses are in the right position, if not
reverse their position
•
Check if the belt is broken or damaged.
2. The Impeller is
turning in reverse
•
Check that the hoses are connected correctly to the hydraulic manifold and
reverse their position if necessary
3. The debris are not
thrown very far
•
The engine is not at full RPM
•
Check hydraulic pump oil level and add some if needed
•
Check hydraulic pump hydraulic pressure, adjust if too low
•
Check hydraulic pump hydraulic flow
•
Reduce the ground speed (Refer to Operation section)
•
Check the hoses for leaks, replace if needed
•
Check hydraulic pump, replace if needed
•
Check the impeller motor; replace if needed
4. The hydraulic motor
of the Impeller leaks
oil from the shaft
•
Check that the maximum hydraulic pressure is below the allowable level
•
Check that the maximum return pressure is below the allowable level
•
Replace the motor seals
•
Replace the motor
