Procedure
- Locate the mounting area as close as possible to the transfer switch and fuel supply.
- Place the unit so air vents won't become clogged with leaves, grass, snow or debris.
- Inspect the generator for shipping damage and if necessary, file a claim with the shipper.
- Make sure the lifting equipment has sufficient capacity to safely handle the generator weight.
- Set the generator onto the pad so the gravel bed extends several inches beyond the generator on all sides.
- Connect an approved ground strap to the grounding lug on the base frame and to an approved earth ground.
- Check the engine oil and add enough recommended oil to bring the level to the FULL mark on the dipstick.
