Operation
Pre-Operation Procedures
Caution: Failure to add oil to the Engine before use will damage the Engine and void the
factory warranty. Engine oil is the key factor in engine performance. Do not use Engine
oil with additives. Do not use two-stroke gasoline-oil. Using these will shorten Engine
life. See Specifications on page 2 for recommended oil type. Also, add 1.5 gallons of
quality hydraulic fluid to the reservoir tank before use.
1. Check that all engine and hydraulic mounting nuts and bolts, and hoses are tight.
2. Check engine oil level (See illustration below, left.) If needed, add oil as listed in
Specifications, Engine, on page 2.
Unscrew the oil Dip Stick and wipe clean. Insert the Dip Stick back into the hole and
screw it in. Remove it again and check the oil level. Full is indicated by oil on the
Upper Level mark. Use a siphon to avoid spilling the oil. Carefully screw the plastic
Dip Stick back into the metal Engine crankcase to avoid stripping the plastic threads
on the Dip Stick.
3. Check Air Filter. Unscrew Air Filter Housing Nut and remove the Air Filter Housing and
Filter Elements. If dirty or dusty, clean. (refer to the Maintenance Section, page 8).
Caution: Never run the Engine without the Air Filter assembly. Damage will occur to
Engine.
4. Check and add hydraulic fluid to the Hydraulic Fluid Tank as needed (up to 1.5
gallons). You can use 10 W AW or Dextron lll automatic transmission fluid. You need
to change the fluid every 100 hours of usage. See photo at the top of page 6.
5. To add hydraulic fluid, pull off the Hydraulic Fluid Fill Tube Cap. Check the level by
reading the attached dip stick. See the photo at the top of page 6.
