= permissible imposed load in tonnes 15 tonnes = acceleration of gravity with 9.81 m/sec.² The permissible load capacities for SAF-HOLLAND fifth wheels and mounting plates (sliders) are specified in the sales catalogue of SAF-HOLLAND. These specifications are applicable for operation on sealed roads and transport conditions common to central Europe.
Operation It is recommended to perform the sliding with an unloaded trailer. Note before unlocking and locking, the vehicle should always be secured against rolling (i.e. by means of a handbrake or wedge placed underneath).

Unlocking and locking the slider (pneumatically operated) The slider is unlocked and locked from the driver cab by means of an operating valve. Warning Pressing the button to release the sliding function (in the driver cab) may only be done if the vehicle is at a standstill! During the sliding procedure, the semi- trailer must be secured with wedges placed underneath it! 1 Press button in driver cab and hold depressed.
Locking incomplete If the locking is incomplete, the indicator pointer (Z) does not cover the indicator field (F)! Tension spring not shown If the coverage is not complete: 1 Release handbrake. 2 Put into first gear and roll slowly f f orward approx. 2 m. The locking wedges slip into the next available pair of teeth (with a brief jerk).
Disassembling the manual locking mechanism Before beginning, fix locking wedges and carriage so they cannot slide (risk of crushing). 1 Release and remove screw 3 Dismantle lever support 2 Unhook spring and remove with bolt 4 Unhook springs (left and right) and remove Align the locking wedges so that the 3 6 Release and remove screws...

The advisory sticker must be attached in a clearly visible position next to the valve. Attach the original SAF-HOLLAND advisory sticker in a clearly visible position next to the operating valve. Accidental covering of the sticker is to be avoided.
Lubrication Before initial commissioning, the positions (D) through (F) should be treated with an oil spray conforming to ISO 22 (not available through SAF-HOLLAND). The use of grease of unspecified quality is not recommended for reasons of uptake and binding with street contaminants: (D) Carriage –...
Maintenance intervals Every 10,000 km Uncouple the trailer and secure it (wedge placed underneath) Clean fifth wheel and slider (use only commercially available cleaning agents specified for the unit) Visual check for damage (especially connecting and moving parts, weld seams) Check carriage guide measurements (see Fig.
