•Wear correct eye and body protection.

Maintenance to be performed only by qualified persons.

A. Cables And Wiring

WARNING: Read and follow safety informa- tion at beginning of entire Section 8-1 before proceeding.

Check interconnecting wiring and connections for tightness and flaws. Be sure that the weld output cable connections are clean and tight. Check the insulation for breaks or other signs of damage. Repair or replace cables or wiring as necessary.

B. Battery

WARNING: Read and follow safety informa- tion at beginning of entire Section 8-1 before proceeding.

Inspect the battery for loose connections, damaged cables, corrosion, cracked case or cover, loose holddowns, and loose or deformed terminal posts.

Clean and tighten connections, replace cables, or replace battery if necessary.

WARNING: Read and follow safety informa- tion at beginning of entire Section 8-1 before proceeding.

The engine is equipped with a full-flow oil filter. Change the oil and filter according to instructions on unit mainte- nance label and in engine Owner’s Manual (Deutz F4L-912 engine). Use correct type and grade of oil as listed in instructions for expected temperature range be- fore next oil and filter change.

This unit is equipped with an oil drain hose secured in a clamp behind the rear panel. A valve is provided in the hose inside the right side base rail. To drain oil from en- gine, remove drain hose from clamp and open valve. Close valve and reinstall hose into clamp before adding new oil.

IMPORTANT: This engine is equipped with an Oil Pres- sure Shutdown gauge/switch and an Oil Temperature Shutdown gauge/switch. If oil pressure becomes too low or oil temperature rises to a level that may cause en- gine damage, the respective gauge/switch shuts down the unit. The shutdown oil pressure has been factory set at 30 psi (207 kPa), and the shutdown oil temperature has been set at 265° F (130° C).

D. Cleaning And Inspecting

WARNING: Read and follow safety informa- tion at beginning of entire Section 8-1 before proceeding.

When performing routine oil changes at intervals specified on the unit maintenance label, clean and inspect the unit as follows:

1.Keep the inside of the welding generator clean by blowing out the unit with clean, dry compressed air.

2.Wipe oil and fuel spills from engine immediately to avoid accumulation of dust.

3.Check for fluid leaks indicating loose oil or fuel connections. Tighten loose connections, and clean oil or fuel spills off engine.

IMPORTANT: See the engine Owner’s Manual (Deutz F4L-912 engine) for complete engine care.
