A 70-litre (15 gal) oil tank was fixed to the chassis frame as hydraulic fluid reservoir.

Per pending federal regulation, there was also a dual master cylinder with separate fluid reservoirs for the front and rear lines.

They could not understand that pouring sand into hydraulic fluid reservoirs would ruin a vital part of the machinery.

Other minor changes included a redesigned engine cover and the power steering fluid reservoir being moved to the front of the engine.

In many vehicles, the essential fluid reservoirs are opaque so you don't have to remove the caps to check them.

The hydraulic fluid reservoir is under the front bonnet/hood.

The rear shocks also changed to eliminate the extra fluid reservoir.

Hydraulic brake levers move a piston in a fluid reservoir.

The fluid reservoir is incorporated in the pump's end cover.

The only portion of the lift that could be malfunctioning is the air line between the control valve and the fluid reservoir.
