7 MINTENNCE ll maintenance should be done as part of the normal servicing of the coach. The oil level should be checked when the vehicle is first purchased and then once every two years. More often if there is an oil leak in the system. ny HWH hydraulic equipment, including jacks, slide-outs and steps should be fully retracted before checking fluid level. The oil reservoir is part of the pump / manifold assembly. The oil level is checked and filled through the breather cap. Clear any dirt away from the breather / filler cap before removing. The batteries should be in good condition and fully charged. ll electrical connections, especially ground connections, should be clean, tight, free from corrosion and protected OIL LEVEL ELECTRICL SYSTEM UNUSUL CONDITIONS The oil level should be within one inch of the top of the reservoir. Most breather caps have a dipstick. Fluid level should be between the bottom of the dipstick and the center mark. NOTE: Overfilling the tank can cause leakage of oil through the breather cap. FLUID: HWH Specialty Hydraulic Oil is recommended. In an emergency Dexron automatic transmission fluid can be used. NOTE: Dexron automatic transmission fluid contains red dye and can cause staining should a leak occur. DO NOT USE brake fluid or hydraulic jack fluid. Use of these can damage seals. from corrosion. Weak batteries can cause erratic operation. attery cable terminals, battery posts and connections should be kept clean and protected from corrosion. If driving conditions are unusually muddy, the jacks may become caked or clogged with mud. This condition may hamper the proper operation of the leveling system. This problem may be prevented or remedied by cleaning off each leveling jack if they become excessively muddy. In west or icy weather leveling jacks may become encrusted with ice. This may cause the leveling system to function improperly. To eliminate this problem, periodically check the leveling jacks and break loose any ice which may be causing improper operation. Do not move the vehicle while the leveling jacks are still in contact with the ground. Place the system in the store mode and then visually check to see if the leveling jacks have returned to the STORE/TRVEL position. NOTE: ll major components of the system can be replaced with rebuilt parts or can be sent to HWH CORPORTION to be rebuilt, when the system is out of warranty. LEVEL SENSING UNIT DJUSTMENT Level the vehicle by placing a circular bubble level in the center of the freezer floor or location within the vehicle that is to be level. With the vehicle level, adjust the sensing unit until all yellow lights are off. This is done by drawing up the corresponding screw if the sensing unit is mounted below the surface as shown or backing out the corresponding screw if the sensing unit is mounted above the surface. ump the sensing unit to see that it is settled tight against all three screw heads and still indicates that the unit is level.
