INSTRUCTIONS FOR ADJUSTING THE LIFTING CHAINS TENSION
FOR STEEL QUICKLIFT • MODEL PEL-400
READ ALL INSTRUCTIONS BEFORE PROCEEDING!
Only trained and qualified service personnel should work on this equipment!
Lock out all potential energy sources before attempting this installation!
1)
Remove any load that is on the machine and run the platform up until it is raised halfway up the mast.
2)
Above the platform, at each end of each chain, locate and turn the four holding nuts (closest to the chains;
item 1) in a counterclockwise direction. (Use a 3/4" wrench on the nut, and a 1/2" wrench to keep the chain
from turning.) Move the nuts as close as possible to the chains ends.
3)
Run the platform all the way to the top of the mast until it stops moving.
4)
Again using 3/4" and 1/2" wrenches, turn each of the four tensioning nuts (closest to the ends of the chain
tensioning bolts; item 2) clockwise until you can only pull the chain 2-1/2" away from the front of the mast at its
midheight. Be sure to turn each nut the same by measuring them for equal horizontal slack dimension.
5)
Lower the platform to the mast, holding the "Lower" pushbutton for two seconds after the platform hits bottom.
If the chains "jump" on the sprockets, tighten the tensioning nuts another 1/2 turn (clockwise) and repeat the
test.
6)
Raise the platform back up halfway to the top of the mast and turn each of the four holding nuts until they
touch against the tensioning brackets (item A), and then tighten each one wrench-tight.

CAUTIONS:
•
Take care to maintain equal tension on both of the lifting chains.
•
Double-check that all four of the holding nuts have been adequately tightened down before placing the
machine back into service.
NOTES:
•
The chain's tension, the tension bolts, and the adjustment nuts should all be checked monthly.
