5. Taking into Service
Daily checks and activities prior to taking into service
If damages or defects are found during the following checks before the
vehicle is due a service they must be eliminated to avoid damage or
danger to the vehicle or operator. Do not operate the vehicle until any
required repairs are carried out. Safety and protective devices should
not be disabled or removed. Do not alter any pre-allocated settings
without recommendation from certified service dealer. Before starting,
make yourself familiar with all the functions and protective devices of
the vehicle. Checking/Cleaning the radiator and protection screens

Taking into Service
-The tyres should not be damaged or worn
-Replace damaged tyres immediately as you dramatically increase
the risk of accident continuing to operate on damaged tyres
Checking Tyre Pressure
Note
Your vehicle can be equipped with different types of tyres. Each tyre
type has its own range of pressure which will depend on the application that the machine is being used for. Remember that tyre pressure greatly affects the maximum speed capability and safe driving
speed of the machine.
Check the inflation pressure on all four tyres. All tyres must read
the same pressure. Low pressure will increase the rolling resistance
and this can cause increased fuel consumption and increase the
wearing of tyres.
Danger
If the inflation pressure is too high, the tyres can explode
Multihog Ltd.

Checking Hydraulic Oil level
Observe the level of the oil in the level gauge ‘1’ to check the level
in the tank. The oil level is correct when the level gauge is half full.
Do not overfill the hydraulic tank.

Adding Hydraulic oil
-Remove the side panel to gain access to the oil filler cap

-Remove the filler cap slowly
-Top up oil to required level slowly
-Clean up and dry any oil spills caused by topping up hydraulic oil
- Replace the filler cap and then refit the side panel
Checking Engine Air Filter Dust Cover
- Remove the Air intake pre filter cover and remove any fine dust
that may have collected in it. Replace the pre filter cover. Check that
the 4 latches are properly closed.

Danger
Safety instructions for handling attachments
The Multihog must be parked safely before starting to attach any of
the attachments. Be aware of all obstacles and surrounding objects
when attaching a new attachment.
During work breaks the attachment must always be lowered
to the ground in order to relieve the hydraulic cylinders. Be aware,
accidents can happen if attachments are lowered in a non controlled
way

8. Operating the Attachments
Regulating the flow with load sensing pump
The load sensing pump is a variable pump for operating attachments with a hydraulic PTO supply of 30L – 120L at up to 220 bar.
You can control the output to the attachment by regulating the
flow through a knob in the cab. You can also regulate the flow and
divide it between the front and rear so as to operate attachments
at the front and the rear simultaneously
For example
30 L to the front (e.g. sweeper)
80 L to the rear (e.g. gritter)
To regulate the flow
- There are two knobs on the roof of the cabin beside the radio,
these are the controls for regulation of flow front and rear.
- For desired front hydraulic PTO output, turn the knob to the marked
output required
- For desired rear hydraulic PTO output, turn the knob to the
marked output required
