SAFETY PRECAUTIONS
Improper use of the GVM leaf collector CAN result in severe per-
sonal injury or death. All personnel using this leaf vacuum must
be trained and qualied with all the operations, maintenance, repair
and safety procedures dened in this manual.
1.3 Training:
The warnings and procedures regarding safety in this manual are to be
used as a guideline only. It is impossible to cover all the events that could
happen in the vacuuming process. For this reason, it is vital that the
owner accept the responsibility to implement a training program that will
provide every operator or mechanic the basic skills and knowledge to make
good judgement in all situations.
This training program must include the entire scope of hazards, precau-
tions and government regulations encountered in the vacuuming process.
The program should stress the need for regularly scheduled preventive
maintenance and detailed equipment safety checks.
GVM strongly recommends all training programs be documented to ensure
all operators and mechanics receive initial training on not just the operation
but the safety features of the leaf collector.

Pre-Operating Section
2.1 Instruments And Control:
Always make sure the PTO is
disengaged before starting unit.
Ignition Switch:
Used to power the accessories and start the unit. Unit will
not start without Murphy switch depressed.
ACCESSORIES - rst position
STARTER ENGAGE - second position (springs return to
rst position)
ENGINE HEATER - left most position - used to heat the
engine
Murphy Switch:
This switch overrides the low oil pressure and high tem-
perature cutoff control. This switch must be depressed
before the starter engages. After the engine starts, wait
for oil pressure to rise before releasing the button.
Tachometer:
This gauge indicates the engine r.p.m’s. The sender is
located on the alternator.
Volt Meter:
The gauge shows the status of the engine charging sys-
tem. When the charging system is operating properly it
should read approximately 14 volts. If the gauge reads
below 13 volts, the alternator is not charging the battery
and the system should be checked by a qualied techni-
cian.
Oil Pressure Gauge:
Conrms and indicates the presence and pressure of en-
gine oil. If the gauge reads low, it should be checked by a
qualied technician.
Engine Temperature:
Indicates the engine coolant temperature. If the gauge
reads over 240 degrees the unit should be checked by a
qualied technician.
Hour Meter:
Indicates the accumulated hours of the engine. This
should be used to schedule maintenance.
