About Safety Locks
Once engaged, Safety Locks hold the Runways in place, even if the power goes out or the Hydraulic
Hoses leak or break. Your Lift has multiple Safety Locks positions, spaced every four inches.
Important
: Simply raising the Runways does
not
engage
them on the Safety Locks. You must
back the Runways down onto the Safety Locks to engage them.
⚠
WARNING
Safety Locks are dependent on correct orientation of the Posts. The Posts must be
oriented so that the Safety Lock Holes are on the far outside of the Lift. If the Posts
are
not
oriented correctly, this could lead to product or Vehicle damage, human
injury, or even (in rare cases) death.

⚠
WARNING
Only leave the Runways either fully lowered or engaged on their Safety Locks. Do
not go under a Lift until you are certain that all four Safety Locks are engaged.
So how do the Runways come down if the Safety Locks are engaged? To lower the Runways, you
raise them a few inches (to get them off the Safety Locks), then
push down and hold down
the
Safety Lock Release Handle and the Lowering Handle. While you hold down the Safety Lock Release
Handle, the Safety Locks are moved away from the Safety Lock Holes; they cannot engaged, which
allows the Runways to be lowered.
Out of an abundance of caution, your Lift has
two
Safety Lock systems:
•
Primary Safety
: The primary system to hold up the Runways are the Safety Locks. When you
move the Runways up, you can hear clicks as the Safety Locks move into and then past the Safety
Lock Holes. When you want to keep the Runways at a certain height, go slightly past the height
you want, then back the Safety Locks down into the Safety Lock Holes, which engages them.
•
Slack Safety
: The Slack Safeties are above the Safety Locks on the ends of the Crosstube
Sleeves. They are different from the Safety Locks in that when the Lifting Cables are taut (during
normal operation), they hold the Slack Safeties away from the Safety Lock Holes so that they
cannot engage. However, if a Lifting Cable were to break (which is extremely rare), the Slack Safety
for the broken Lifting Cable immediately engages, which prevents the Runway from falling very far.
