Service
STEP 1: Remove the safety catch pin from the top of the frame. Insert a hook into the chain
links welded to the top of the hammer, and lift out the hammer with a hoist,
forklift, or another vehicle. Lay the hammer on the ground.
STEP 2: Disconnect the hydraulic hoses, and remove the Postmaster/Slab Blaster from the
vehicle.
STEP 3: Carefully lay down the Postmaster/Slab Blaster on its back.
STEP 4: Remove the front cover.
STEP 5: Remove the chain. (The drive chain has been welded together and must be cut off.)
STEP 6: Loosen the bolts on the bearings, allowing the sprockets to slide closer together for
reassembly.
STEP 7: Check the alignment of the sprockets by measuring the distance from each side
of the sprocket to the frame on the upper and lower sprocket. Then place a straight
edge on the side of the sprockets from the upper sprocket to the lower sprocket to
ensure straight alignment.
REPLACING THE DRIVE CHAIN
Check sprockets and nylon guide plate for wear and replace if necessary.
