ant-lubricant flow (figure 13).
Do not use the magnetic core drill unit when
the cooling-lubricant system is defective. Each
time before operating, check for tightness
against leaks and for cracks in the hoses. Pre-
vent liquids from entering or penetrating elec-
trical components.
Insert the hose into the cooling-lubricant con-
nection of the machine.
The cooling-lubricant flow is actuated by
operating the hand pump.
When working overhead, use a cooling-lubri-
cant paste from Slugger.
When drilling overhead, make sure that the
battery is properly engaged and can not fall
out.
