Check the cooling fluid of the cylinder liner

Check the liner’s nozzle everyday to avoid
jam and to make sure the liners and pistons are sufficiently cooled and
lubricated.
5.
Loosen the piston rod clamp daily and turn
the piston quarter round then tighten the rod clamp to make piston wear equally
and prolong the life of liners and pistons.
