Maintenance Tips
-
Check fluids before use: Inspect and top off engine oil and hydraulic fluid before each session; correct levels help maintain power and prevent damage.
-
Clean and protect: Keep the beam, frame, and engine area free of dirt, wood chips, and debris; clean and dry after use to prevent corrosion and buildup.
-
Inspect hoses & fittings: Regularly check hydraulic hoses, hoses clamps, and fittings for leaks, cracks, or wear and tighten or replace as needed.
-
Grease moving parts: Lightly lubricate pivot points, wheel bearings, and other moving parts periodically to ensure smooth operation.
-
Tire & fastener care: Maintain proper tire pressure and periodically check that all nuts, bolts, and hitch components are tight.
-
Annual hydraulic service: Replace or refresh hydraulic oil at least annually (or per manufacturer schedule) to maintain optimal pressure and performance.
-
Store properly: Before storing for long periods, clean the unit, relieve hydraulic pressure, and store in a dry place; add fuel stabilizer or drain fuel to prevent gumming.
