If your coach is a 2000 year model or later and you have slide room extensions, checking the proper level of the reservoir depends on the type of extension mechanisms used in your particular year model coach. When adequately filled, the oil level of the reservoir will be approximately one inch below the top of the reservoir.
FLUID: HWH Specialty Hydraulic Oil is recommended. In an emergency Dexron, automatic transmission fluid can be used.
NOTE: Dexron automatic transmission fluid contains a red dye and can cause staining should a leak occur.
DO NOT USE brake fluid or hydraulic jack fluid. The use of these can damage seals.
It is important that all front rooms are fully retracted before checking the hydraulic oil level.
If the coach has a bed slide, the bed slide must be fully retracted before checking the hydraulic oil level.
If the coach has a wardrobe slide, the wardrobe slide must be fully extended before checking the hydraulic oil level.
To check the oil supply, remove the breather cap from the top of the hydraulic oil reservoir. The oil level should be approximately one inch below the top of the reservoir when adequately filled.
