• PERIODIC MAINTENANCE SCHEDULE •
The following information contains the maintenance and operations procedures that must be
adhered to improve the life of your machine. A well maintained piece of machinery will provide you
years of satisfaction.
•
Use Loctite anti-seize MIL A 907D to lubricate the top pipe coupler threads before assembly.
•
Oil winch bushings at 10 hr. operation intervals. Use light lubricating oil.
•
CAUTION! Change worn or frayed cables - cables under tension may snap and cause severe
injury. Use proper methods illustrated in this manual to properly attach cables. Always connect
cables properly - wrap cable under last form pin then connect cable hook to the next form pin
towards the screed.
•
DO NOT hook cables to a stake driven into the ground, the stake can tilt and allow cable under
tension to snap back and cause severe injury.
•
CAUTION! For screeds over 75 ft. in length consult the factory.
•
Check your screed for loose bolts and nuts approximately every 30 to 45 days.
•
Make sure that all the vibrator nuts and bolts and also the nuts on top of the vibrators themselves
are still tight, because these can and occasionally do loosen through vibration.
•
Always check the air hoses to make sure that none of them have been broken or severed
somehow. Usually this is done by a shovel or come-along during the pour.
•
It is almost impossible to get dirt or grit into the vibrators, but if this should happen, wash the
vibrator out promptly with a cleaner. To clean the vibrator, remove it from the machine and
replace it with a spare one. Remove the top nut and also the piston. Clean the vibrator with a
vibrator cleaner and wipe it dry with a clean cloth. Oil the piston, place it back into the barrel and
tighten the top nut. Tighten the top nut until you see the nut dig into the brass on the barrel
section. Now your vibrator is ready for re-use.
•
To provide proper air supply should be dry and contamination free. Clean dry air will provide
trouble free vibrator operation.
•
If the air compressor is fitted with an air dryer, the moisture content of the air supply will be
reduced. The reduction should be less than 10%. This will enable Allen's A88/NR oil to absorb
the remainder of the moisture in the air stream. If the air stream is not dry, the moisture will
combine with the vibrator lubricant to form a sticky sludge. This results in vibrators slowing down
or in cold weather, not working.
