WARNING! SAFETY CHAINS MUST BE CONNECTED TO SECURE ATTACHMENT
POINTS ABLE TO WITHSTAND THE PULLING FORCE OF LOADING. THEY MUST
ALSO BE TAUT ENOUGH TO PREVENT THE RAMP FROM COMING OFF THE VE-
HICLE BEING LOADED.
Pull the loading ramp back until the chains are tight. If most of the edge or the entire4.
edge of the ramp is off of the edge of the vehicle the chains need to be adjusted or
shorter chains must be used.
Chain Adjustment:5. Remove the bolt and washer that hold the safety chain to the ramp.
Reinsert the bolt through a link that will shorten the chain so the loading ramp can not
be pulled backwards by the ATV’s rear tire more than an inch or two. Make sure that
the bolt is properly tightened and the washer prevents the bolt from slipping through the
chain link. Adjust the other chain to equal length.
