level falls below LOW mark, remove the cap (Fig. 3) and refill with new clean grease.
Warning! Never use used grease.
4 Maintenance
iSHAN centralized lubrication system is easy to maintain. The reservoir must be
cleaned before installation and in service time so clean the reservoir regularly. If there is
any impurity or oil sludge found at the bottom of reservoir or on the strainers of the
lubrication unit, disconnect the product from main power supply and take off the
reservoir by removing 4 screws on the corners. After the reservoir is cleaned, assemble it
to the lubrication unit.
