PLANNED MAINTENANCE
2-11
Check Tilt Cylinder Racking

WARNING
Tilt Cylinder Racking and Tilt Degree
Settings
Racking occurs when the tilt cylinder strokes are uneven,
(one cylinder bottoms before the other). The mast rails
then twist, eventually causing them to crack and
separate.
Proper tilt degree adjustment is 3° forward and 3° to 3.1°
backward maximum for masts less than 240".
For masts above 240", tilt no more than 2° forward and 1°
backward.
Racking
To check for racking:
1. Locate a reasonably level floor area to park the
forklift.
2. Set the key switch to “ON” and shift the mast to the
center of the forklift, as viewed from inside the
driver’s cab.
3. Raise the forks about 36” (914 mm) from the floor
and tilt the mast fully forward.
4. Tilt the mast forward and rearward a few times.
Carefully watch as the mast completes the forward
and backward stroke, checking for twisting (racking).
5. If there is any twisting motion (racking) of the mast
rails when the cylinders “dead-head,” both tilt cylinder
rods must be re-adjusted. See following Step 10 “To
adjust for racking.”

CAUTION
6. Trial and error is the most effective way to check this
adjustment.
7. Repeat steps 4 and 5 a few times to be sure what
type of adjustment is needed.
8. One cylinder may need tightening while the other
needs loosening, or one cylinder may need a minor
adjustment.
9. To check degree of tilt, be certain the forklift is on a
smooth, level surface.
10. Tilt the mast back its full stroke.
11. Place a tilt gauge against the rear outer mast rail on
the right side of the forklift. See Figure 2-13.
12. The gauge must read between 3.0° and 3.1°
maximum for masts less than 240" (1 ° for masts with
MFH greater than 240") . See Step 2 on page 2-11
“Tilt Degree Adjustment” if adjustment is needed.
13. To adjust for racking, tilt the mast fully backward.
14. Set the key switch to “OFF” and remove from key
switch.

WARNING
15. Loosen tilt cylinder jam nut using a 1-3/4” open end
wrench. See Figure 2-14.
16. Adjust each tilt cylinder rod accordingly, using a
1-1/8” (28.6 mm) open end wrench, by turning
clockwise to shorten the stroke or counterclockwise
to increase the stroke
.
17. Turn the rod only a 1/4 turn at a time until the correct
setting is achieved.
18. You may have to tilt the mast a number of times
(repeating Steps 10 through 13) until the adjustment
is correct.
• When checking any of the mast functions
keep everyone away from the forklift.
Movement of the mast or other components
may injure unaware bystanders.
• Review the Safety chapter at the beginning of
this manual.
• The following adjustment procedures are
critical and must be maintained for optimum
forklift performance.
If this is left unattended, serious damage to the
mast assembly or the tilt cylinders can occur,
causing extensive repair and downtime.
DO NOT service the tilt cylinders while the key
switch is “ON”. If steering wheel or drive pedal is
accidentally moved, someone could be caught
between the mast and the forklift, causing
serious injury.
