ENGINE BREAK-IN
All new engines require a break-in period. The
service life of your engine is dependent upon how
your engine is operated during the first 50 hours of
operation.
1. ALWAYS idle and warm up your engine
for at least one minute. In cold weather,
allow the engine to warm up completely
before operating the unit.
2. NEVER overload the engine.
3. Change oil after the first 8 hours for
gasoline engines and after the first 50
hours for diesel engines:
With the engine stopped and warm, drain
the crankcase and remove oil filter. Install
a new oil filter and refill the crankcase with
proper oil.
WARNING
• This oil change must be performed as
specified and only by properly trained
service personnel.
4. Refer to the Maintenance Guide for future
service intervals.
FREE WHEELING OR TOWING UNIT
To prevent damage to the pump or wheel motors
when FREE WHEELING or TOWING:
1. Engine must be OFF and cool.
2. Turn hydraulic pump lever on bottom of
pump 180
°
counterclockwise to open
position (as viewed from the bottom).
3. FREE WHEEL or TOW unit slowly, below
2 mph (3.2 Km/h).
4. Before starting engine, be sure to turn
pump lever clockwise to fully closed
position.
NOTICE
• If pump lever is not completely closed, a
significant loss of speed will occur.
Operating the unit when the pump is not
completely closed, may cause damage to
the pump.
SERVICE & MAINTENANCE
840748
Keep hands out of moving parts. Shut off the engine
and remove the key before servicing equipment.
WARNING
• When replacement parts are required, use
genuine Ransomes parts or parts with
equivalent characteristics including type,
strength and material. Failure to do so
may result in product malfunction and
possible injury to the operator and/or
bystanders.
• Never attempt to perform service or
maintenance functions on the unit if you
are UNTRAINED or UNAUTHORIZED.
Improper maintenance can cause
hazardous conditions. See your authorized
dealer for necessary maintenance and
service.
• When it is necessary to raise the unit for
any repair or service, use jackstands to
provide adequate support. DO NOT rely
on hydraulic or mechanical jacks.
• Always replace any warning decal that
becomes hard to read.
FUEL RECOMMENDATIONS
Fuel tank should be filled to within 1/2² (13mm)
below the bottom of the filler neck. DO NOT over fill
the tank.
DIESEL FUEL RECOMMENDATION
Use #2 diesel fuel (ASTM No. 2D) when
temperature is above 20°F (-7°C).
Use #1 diesel fuel (ASTM No. 1D) when
temperature is 20°F (-7°C) or below.
NOTICE
• NEVER use No. 2D at temperatures below
20°F (-7°C) unless you are sure it has
been “winterized”. Cold temperatures will
cause fuel to thicken which may keep your
engine from running.
• If No. 1D is not available, a “winterized”
blend of No. 1D and No. 2D may be
available. This blended fuel is usually
called No. 2D also and may be used in
colder temperatures.
• If the vehicle fuel tank is being filled for
the first time or if the vehicle was allowed
to run out of fuel, it will be necessary to
bleed the air from the fuel system (refer to
“Bleeding The Fuel System” ).
