Diggingtips

When planning and carrying out digging work, we recommend the following:

•Exits from pits should be outside the digging line and should be as level as possible.

•Dig by removing adjacent strips if possible.

•Make sure you can drive forward when driving out of the digging area with a fully loaded bucket.

•Whenever possible, drive in reverse when transporting a full bucket down a steep slope.

Loadingtrucks

When loading trucks, we recommend taking the following into account:

•If possible, the truck and the working direction of the machine should form an angle of 45°.

•Only raise the full bucket to the dump height when you are driving in a straight line towards the truck.

•If possible dump with the wind behind you to keep the dust away from your eyes, air filters and fans.

Freeingthewheelloader If your machine gets stuck in soft ground:

☞ Dump out the bucket until the blade is vertical above the ground.

☞ Lower the telescopic unit all the way.

☞ Gradually tilt back the bucket.

➥ The machine is pushed rearward.

☞ Reverse slowly.

☞ Repeat this procedure until the wheels reach firm ground.

☞ Reverse the machine away.

Fittingtheattachmentontothequickhitchfacility

☞ Pick up the attachment

➥ –see Locking: Attachments without hydraulic function on page80

☞ Make sure both pins of the lock ram are safely locked into place in the attachment.

WARNING!

The attachment must always be safely locked onto the quickhitch facility –Accidentrisk.

☞ Before working, make sure that the attachment is safely locked onto the quickhitch facility by using the lock cylinder. You must be able to see the lock pins on both sides of the mounting holes on the attachment.

Removingthepalletforksfromthequickhitchfacility

WARNING!

The attachment must be placed on the ground so that it will not fall over when removed –

Riskofpersonalinjury.

☞ Position the attachment so that after unlocking it will stand safely and not tip over.

Adjustingtheforkarms

WARNING!

If the fork arms are not secured to avoid lateral sliding or slipping –Accidentrisk.

☞ Before using the pallet forks with or without load, check whether both locking levers on the fork arms are folded down. This locks the safety pins of the fork arms in the notches on the fork frame, and prevents the fork arms from slipping or sliding sideways.

When the fork arms are moved under the load, they must have the greatest possible spacing between them, and must always be evenly aligned with the fork frame.

To achieve this, the spacing of the fork arms can be adjusted as follows:

☞ Set the locking lever to the vertical position a

➥ The fork arms can be moved on the fork frame.

☞ Slide the fork arms to the required distance until the safety pin engages in a slot on the fork frame.

☞ Fold down locking lever again, position b

➥ The upper edge of the locking lever must be flush with the edge c

IMPORTANT!

Locking mechanism must be replaced immediately if damaged.
