Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use.
For vertical mounting, install lock nut on piston rod end.
Maintain 0.5mm minimum clearance between rod end and load.
Avoid side load exceeding 30N. Maximum permissible lateral force:
1/20 of theoretical thrust. Use guide mechanism if lateral forces exceed limit.
