11. a) Install the supplied band clamp to compress
the inner wire ring on the head/gland assembly
so it will fit into the tube.
Note: Make sure the cam of the band clamp is
not overtop of the gap in the ring.
12. Lubricate the cylinder tube and piston seals.
13. Insert the piston into the tube. Tap the cylinder
head into the tube until the clamp slides over
and the inner wire ring is inside the tube.

Flush with edge
16. Tap the head the rest of the way until the end is
flush with the tube.
IMPORTANT: The head/gland must be inserted until
it is flush with the tube to allow the inner wire ring to
snap into its seated position in the internal cylinder
groove. Failure to insert the head flush as shown will
result in the head and rod assembly coming out of
the tube when pressure is applied to the cylinder.
17. Pull the rod out to expose the external wire ring
groove in cylinder head, and then install the
external ring.
18. Before using the cylinder, ensure that you double

1. Failure to follow proper procedures when
mounting a tire on a wheel or rim can produce
a blow out which may result in serious injury or
death.
2. Do not attempt to mount a tire unless you have
the proper equipment and experience to do the
job.
3. Have a qualified tire dealer or repair
serviceman perform required tire maintenance.
TIRE SAFETY
The landroller should be carefully prepared for
storage to ensure that all dirt, mud, debris and
moisture has been removed.
Follow this procedure when preparing to store:
1. Wash the entire machine thoroughly using a
water hose or pressure washer to remove all
dirt, mud, debris or residue.
2. Inspect all parts to see if anything has become
entangled in them. Remove the entangled
material.
3. Lubricate all grease fittings to remove moisture
(except spherical bearings - refer to pg.11)
4. Inspect all hydraulic hoses, fittings, lines and
couplers. Tighten any loose fittings. Replace any
hose that is badly cut, nicked or abraded or is
separating from the crimped end of the fitting.
5. Touch up all paint nicks and scratches to prevent
rusting.
6. Oil the exposed rams on the hydraulic cylinder
to prevent rusting.
7. Select an area that is dry, level and free of
debris.
STORAGE
AUTOFOLD LATCH ADJUSTMENT
If the Autofold Latch will no longer fully open
enough to release the Swing Arm for transport, this
may be due to the slight stretching of the autofold
cable. To Adjust:
1) Place Landroller into Field Position (wings
out) with the Swing Arm in the latched (secured)
position.
2) Lower the wheels raising the drums off the
ground. (This should open the Autofold latch in
order for the Swing Arms to release. If the latch
does not open enough to allow the swing arm(s) to
release, continue to the next step.)
3) Adjust the nut on the Eyebolt until the latch is
open just enough for the Swing Arm to clear. This
should be the correct amount of tension for the
cable.
