WARNING: Heavy objects! Lift and handle all heavy components using lifting equipment with adequate capacity. Always support units or parts with suitable slings or hooks. Make sure the work area is clear of all bystanders. Failure to comply could result in death or serious injury.

Raise hood using controls located behind the access cover.

Turn master electric switch to the off position after hood is raised.

Remove bolts (1) from exhaust stack on the underside of hood, then remove plate (2).

Double up a nylon lifting strap. From the topside, slide looped strap through the hood exhaust opening.

Place a solid steel bar through the strap loop (see arrow) and tighten. Attach the other end of the strap to a suitable lifting device and remove any slack in the line.

Remove cotter pin and pin from the lift cylinder. Turn electrical master switch back on and run lift cylinder up. Once cylinder is retracted, return the electrical master switch back to the OFF position.

Remove the hood bracket bolts and move hood away from back plate, allowing enough clearance to reach air cooler unit front bolts.

Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and twisting, which would jeopardize sealing efficiency.
