4.1.3. KICK-UP (or Roll-Under).

Hook up to the straightener

and pull as in figure 15.

4. INSTRUCTIONS FOR USE

 WARNING! Only fully trained and qualified persons should use this equipment. These instructions are not a substitute for the user receiving

full supervised training by a qualified technician. It is very important the user understands this products applications, limitations, and specific

potential hazards. Ensure health & safety, local authority, and general workshop practice regulations are adhered to when using this

equipment and that you read, understand and apply the safety instructions.

In all cases, when the final pull is complete, re-check all dimensions to ensure they are equal to the manufacturer's specifications.

4.1. CHASSIS (FRAME) STRAIGHTENING

4.1.1. SAG

To repair SAG place the main beam of the straightener under the vehicle and chain the

frame to the beam. Place a jack between the beam and the frame at the centre of the

SAG area and jack upwards while at the same time pulling the frame forward (fig 10).

To avoid irregularities in frame alignment always use a combination of PUSH AND

PULL when correcting SAG. If both frame rails are sagged, straighten one at a time.

Then check with gauges to ensure the frame is in line. If not repeat the operation.

4.1.2. SWAY

a) General hook up.

Place the straightener beneath the frame and anchor frame on both sides at

points according to figure 11. On vehicles with low rocker panels it may be

necessary to place wooden blocks between the chain and the floor panel to

protect the body work.

Make the final pull a little beyond centre alignment to allow for spring back

in the metal.

b) Front & Rear end Sway (fig 12).

Wedge the anchor post against the frame. If there is nothing to anchor against,

wrap chain around the frame and the post, (ensuring you follow safety

precautions) or weld a temporary steel support to the frame. When the task

is complete, remove the steel support.

Should the straightener lift from the floor during pulling, place an appropriate

wooden block between the beam and the frame to hold the unit in position.

c) “X” or Hourglass frame sway.

Such frames are usually bent at one end, the central section remaining aligned.

Hook up for straightening as in figure 13.

If the vehicle is raised high enough, the chains will slam down and clear the

rocker and fender panels. Figure 13 shows only one method of hook up.

Various hook ups may be used to suit the particular type of damage. To avoid

stretching the frame to far, it may be appropriate to weld hook-ups and attach

an appropriate length of chain between the front and rear of the frame as in

figure 14.

4.1.4. DIAMOND.

Frames can be straightened by using the same general hook-up as for front

and rear end SWAY. The extension beam is pulled out to make a

hook-up as in figure 16.

4.1.5. TWIST.

Ensure any other type of damage is completed before attempting to correct a

twist. To repair twist, place the straightener (fig 17.A) diagonally under the frame

(B) with an 8’ section of heavy I-beam (C) balanced on top of the straightener

forming an “X” below the vehicle. Chain the I-beam to the straightener (D) to

prevent lifting and slipping. Chain the high points of the frame to the I-beam (E)

and place hand jacks on the beam (F). Start to raise one jack a little on one

side, then the other side. DO NOT over extend one jack too far beyond the other

jack or you may further damage the frame.

fig.9

To use the hydraulic pump, turn the side valve clockwise to close (fig 9).

To release the hydraulic pressure, slowly turn the valve anti-clockwise.

Before first use.

Before using the pump for the first time, purge hydraulic circuit in order to eliminate any possible air that may have accumulated during transit.

To do so, connect the pump and ram. Put the pump on a workbench and fully pump out ram. Put ram upside down on the ground, open valve,

close ram and pump 8-10 times with the valve open.
