MAINTENANCE

Important: Use only good grade hydraulic jack oil. Avoid mixing different types of ÀXLG and NEVER use brake ÀXLG

turbine RLO transmission ÀXLG motor oil or glycerin. Improper ÀXLG can cause premature failure of the jack and the

potential for sudden and immediate loss of load. We recommend Mobil DTE 13M or equivalent.
