General Shop Rules
• Always use the right tools for the job, otherwise components may be
damaged.

other.

• Keep component parts together as a group. Assemble screws and nuts
into appropriate subgroups.
• When reassembling, clean all parts carefully, lubricate moving parts and
replace all oil seals, o-rings, gaskets, washers and self-locking nuts.
• For best results, use only original ICS®replacement parts.
