MAINTENANCE AND LUBRICATION INSTRUCTIONS
NOTE: All engines and hydraulic reservoirs are shipped WITHOUT oil.
ENGINE: The engine is shipped without oil or gasoline. Refer to the manufacturers instructions for
proper procedures and recommended fluid.
HYDRAULIC FLUID AND FILTER: The hydraulic reservoir should be filled to the top of the sight gauge
with hydraulic oil before attempting to start the engine. Most premium grade, mineral based oil with anti-
wear (AW) and anti-foaming additives are suitable. The recommended fluid for normal temperature
operation is ISO VG 46 grade fluid. In colder climates use ISO VG 32 grade and in warmer climates use
ISO VG 68 grade fluid. The hydraulic oil and return line filter (Part # 30280) must be kept clean at all
times, and should be changed after the first 15 hours of operation. The filter and oil should be changed
every three months or after 100 hours of operation; whichever comes first.
NOTE: The hydraulic fluid and engine crankcase oil levels should be checked prior to each
days use.
IMPORTANT: All nuts, fasteners, and fittings must be kept tightened. If the engine or tank
mounting bolts are allowed to loosen, premature coupling and/or pump wear may result.
CAUTION: Escaping hydraulic fluid under pressure can have sufficient force to penetrate the
skin, causing serious injury. Before disconnecting hydraulic lines, be sure to relieve
pressure. Before applying pressure, be sure connections are tight and fittings, pipes and
hoses are not damaged. Use a piece of cardboard or wood, rather than hands, to search for
leaks. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can
develop if proper medical treatment is not administered immediately.
KEEP all hydraulic lines away from moving parts.
HYDRAULIC OIL LEAKAGE
If any hydraulic oil leakage is encountered, shut down the power source and relieve the hydraulic
pressure by moving the throttle valve in both directions. Check and tighten the screw-on fittings on the
end of each hose. If the leakage persists, it may be necessary to replace the associated hose assembly.
If one of the Quick Disconnect fittings is the source of leakage, the quick disconnect coupling should
be replaced. If the throttle valve is leaking around the spool (shaft), you may replace the seal kit (Part
# 30275-2).
NOTE: To obtain maximum performance from power source, minimum hose size
recommended is 3/8".
HYDRAULIC HOSE ASSEMBLY REPLACEMENT
WARNING: For power source serial numbers from H-0001 through H-3252, do not exceed
the following maximum hose assembly lengths. Longer hose assemblies may allow the torque tube
to uncouple, causing serious personal injury.
If replacement hose assemblies are required, the maximum overall length of the pressure/return
hose assembly on the handle is 36". The maximum overall length of the pressure hose assembly on
the power source is 74
power source is 68".
EXCESSIVE HEATING
Excessive heating is caused by placing too much down pressure on the auger which causes the oil
pressure to reach relief pressure. Oil flowing over the relief valve generates the heat.
DECAL LOCATION
The decals which are provided with your machine are shown at the rear of this manual. The decals shown
should be in the locations as described. If any of the decals are missing or illegible, order replacement
decal kit # 30181-D# and install before operating the machine.
