3.4.3.2 Raising the Trailer Body TT2515 (Manual pump)
•
Insert the pump handle into the
pump mechanism.
•
Close pressure release valve by
turning the release valve clockwise.
•
Pump the handle until body has
reached desired height.
3.4.3.3
–
Lowering the Trailer Body.
•
Ensure that the area between the chassis and platform is clear of obstruction.
•
Slowly open pressure release valve by turning anti-clockwise. Control the rate of decent by
adjusting the valve position.
•
If the release valve is opened too quickly too soon the flow of high
pressure hydraulic fluid out
of the ram may be such that it simulates a bust hose and the burst valve screwed into the base
of the ram then closes, locking the trailer in a partly tilted condition.
•
Once the body is fully lowered, ensure the pressure release valve is left open to avoid a build-
up of pressure in the hydraulic system.
•
On TT2012 ensure body catch has fully engaged.

–
Side Discharge
•
Ifor Williams Tipping Trailers do not side-tip but it may often be convenient to open the
sideboards on one side to shovel off aggregate loads or, if the side centre pillar is removed, to
roll or drag other cargo off the side. N/A for TT2012
