OPERATION
POSITIONING THE JACK STANDS
WARNING! Do not place your body under the vehicle to position
jack stands as the vehicle may slip off the floor jack and cause
serious damage or death.
WARNING! Ensure the jack stand’s saddle matches the shape of
the support points to permit a solid contact. A mismatch may
cause the vehicle to slip off the jack stand and cause serious
injury or death.
NOTICE! The jack stand’s legs may damage the floor surface
when holding a vehicle. Place a 1/4 in. sheet of plywood or a
rigid metal sheet underneath the jack stand’s legs to distribute
the weight.
1. Use jack stands in pairs to support the vehicle. Both jack stands
must support the same point at the same height on either side of
the vehicle.
2. Place the jack stands under areas of solid metal:
2.1 Vehicle frame.
2.2 Frame rails. A frame rail prevents the vehicle’s undercarriage
from colliding with road obstacles. A rail runs the length of the
vehicle on each side and may resemble a metal seam.
2.3 Wheel axle.
2.4 Steel cross-member.
3. Once in position, lift the saddle until it is directly under the vehicle’s
support point.
3.1 Pull the ratchet bar upward. The ratchet teeth will slide past the
pawl. The handle will rise and fall as the ratchet bar is moving
upward.
3.2 When positioned below the support point, ensure the handle is
in the down position. If not, move the ratchet bar up and down
slightly until the handle settles. A click can be heard when the
pawl is in place.
3.3 Release the ratchet bar and push the handle down to confirm
it is in place.
