COOLANT REPLACEMENT
The trim saw tank on the Cab Combo Workshop requires periodic routine maintenance to remove and
properly discard the build-up of rock mud, sludge and dirty lubricating fluid (oil) from the oil tank reser-
voir. It will be apparent to the user after prolonged sawing that the lubricating fluid is dirty and needs
to be changed if the oil residue on the saw table (after cutting) is thick and dark with rock sludge
build-up.
The oil liquid can be removed rapidly by removing the square-head drain plug attached to the bottom
drain hole at the base of the coolant reservoir (fig 61). The oil should be collected in a container and
either reused or properly disposed of.

To prevent the overflow of oil and rock sludge onto the baseboard or floor, use a bucket or collec-
tion container placed under the baseboard to allow the free flow of oil and sludge into the bucket for
proper disposal. The thicker solid sludge residue in the tank will likely not flow through the 1/4" diam-
eter drain hole. Therefore the sludge should be removed after the slab saw oil lubricant is drained, by
removing the saw tabletop and extracting the sludge with a spatula or spoon.
Once the sludge is removed, wipe the inside of the tank with disposable towels and refill the cut-
ting lubricant to cover 1/4" of the bottom edge of the blade (fig 62). The diamond blade should be
removed from the arbor shaft while removing the sludge. Be sure to check the coolant level inside of
the reservoir after every 3 to 5 hours of use as the fluid will absorb onto the rock material and will be
reduced over time due to heat and evaporation.
BELT
The Cab Combo Workshop arbor is driven from the electric motor by a AX-24 rubber belt. The Belt
tension is adjusted at the factory. However, if it is necessary to service this belt, unplug the Cab
Combo Workshop from its power source and remove the fasteners that secure the belt guard housing
to the motor. The belt tension should be checked periodically by removing the guard and depressing
the belt in the middle between both the motor and blade arbor 2" OD pulleys. There should be 1/2" of
