6. MAINTENANCE
To insure reliable service from your Rod Pushing Machine, we recommend the unit be com-
pletely serviced every 6 months.
TRACTOR DRIVE
Inspect the chain drive blocks for wear each week.
CHECK
the chain tension weekly and adjust if necessary with the two
external adjustment screws (do not over tension). The chain should
slightly lift off the chain guides, when pulled at the center by finger.
THE CHAIN SHOULD BE LUBRICATED EACH TIME USED
by application of Metaflux
spray grease 70-88. This is achieved by running the rod pushing machine at about 130ft/min
without any rod and carefully inserting the spray tube from the canister into the holes on the
operator side of the aluminum drive castings (2). The spray tube should be carefully inserted
until the chain can just be felt and then withdrawn about 3/4 – 1” and spraying for approxi-
mately 1 second.
DO NOT OVER LUBRICATE, AS THIS MAY LEAD TO THE DRIVE BELTS BEING
CONTAMINATED WITH LUBRICANT.
If contamination does result, wipe the belts clean thoroughly before attempting any pushing
operation. (This is based on normal use where the chains are not exposed to excessive
contamination).
