If possible, grease both ends of the cable and move the controls to end stop positions when lubricating. 
Refit the rubber covers on the cable after lubrication. Cables with sheaths will bind if they are not lubricated 
regularly. If a cable binds, it can disrupt operation.

If a cable binds, remove the cable and hang it vertically. Lubricate it with thin engine oil until the oil begins 
to escape from the bottom. 

Tip: Fill a small plastic bag with oil and tape it so that it seals against the sheath and allow the cable to hang 
vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.

The hydraulic oil and filter shall be replaced 
every 300 hours, and at least once a year. 
Contact an authorized service workshop.

Check the oil level in the hydraulic tank daily. 
The level should be about 3/4"-1" below the 
top of the tank.

Check connections, hoses, and tubes for 
damage or leaks. Replace or repair if 
doubtful.

Oil and filter changes should be carried out 
by an authorized service center.

Tip the seat.

Lubricate the linked mount at the front using 
an oil can.

Lubricate the lengthways adjustment 
mechanism with the oil can.

Lubricate the lengthways adjustment runners 
with the oil can.
