Workingwiththemachine

Generalsafetyinstructions

•Never drive up to the edge of a pit from the outside – risk of cave-in.

•Never undermine the foundations of walls – risk of collapse.

•When excavating, look out for high-voltage and underground cables, and gas and water pipes.

•When using lifting gear such as pallet forks, comply with the load diagrams –see Load diagram on page71.

•The hydraulic system of the machine is still pressurized even when the engine is not running. Depressurize the sections of the system and hydraulic lines that you want to open before starting setup or repair work (e.g., fitting/removing an attachment with hydraulic functions) –see Depressurizing the quick couplers on the telescopic unit on page78

•If your machine is equipped with a load stabilizer:

IMPORTANT!

Turn off the load stabilizer before working with the telescopic unit. If you leave the load stabilizer on, the lifting capacity of the telescopic unit is only about 60% of the rated force, and it is difficult to complete precise lifting movements.

Loaddiagram

Follow the load diagram when using pallet forks with fork arms on the telescopic unit. The telescopic unit with fork arms moves within the shaded range. The load diagram states the rated operating load on the fork arms. The maximum load varies according to the horizontal distance of the load center to the front edge of the tires.

The diagram is divided into four shaded sections to show the movement of the telescopic unit. The distance between the center of the load and the rear side of the fork arms is 24” (610mm).

Example:

•Off-road applications ➝ safety factor S=2.0

➥ Load distance to rear side of fork arms = 24” (610 mm).

•Height of fork arm above tire contact area = 4’9” (1.50 m).

•Distance to front edge of tires = 9’2” (2.80 m) (range B).

•Maximum load is 1997 lbs. (906 kg).

IMPORTANT!

The load diagram in the cab is valid only for use with the pallet forks with fork arms as specified –see Fields of application, attachments on page9. Follow the specific load diagrams of other attachments used.

Safeloadindicator

DANGER!

The safe load indicator has been set for industrial applications (S=1.25). Do not rely on the safe load indicator when working off-road –Accidentrisk.

☞ Adapt your drive speed and loads to the terrain. Refer to the load diagram for the maximum authorized loads.

A defective safe load indicator or working at more than 100% of the safe work load may cause the machine to tilt –Accidentrisk.

☞ Check the safe load indicator daily.

☞ A flashing indicator and acoustic signal warn of loads exceeding 100%. Reduce the load to below 100% by retracting the telescopic unit.

The telescopic loader is equipped with an el ectronic load indicator that continuously monitors weight changes on the rear axle during operation.

Visible and acoustic signals warn the operator of critical loads on the telescopic unit that may cause the machine to tilt forward.

IMPORTANT!

Critical side loads are not monitored, i.e., the operator is not warned of critical side loads.

The LEDS a, b and c indicate the percent of the load on the telescopic unit that is the safe work load: a Six green LEDS – indicates loads between 35 and 100% of the safe work load. b Two yellow LEDS – indicates loads over 100% of the safe work load. c Two red LEDs – indicates loads up to 122% of the safe work load. d Green LED to signal readiness. e Tip switch for checking the system. f Mute switch for adjusting the volume of the acoustic signal.

Depressurizingthequickcouplerson thetelescopicunit

IMPORTANT!

The hydraulic system of the machine is still pressurized even when the engine is not running. The hydraulic quick couplers can be released, however they cannot be re-attached because the hydraulic lines are not depressurized. Therefore:

☞ Depressurize sections of the system and hydraulic lines that you plan to open before starting setup or repair work, e.g., fitting/removing an attachment.

Depressurize as follows:

☞ Apply the parking brake

➥ –see Parking brake on page50.

☞ Unlock the 3rd control circuit

➥ –see Locking the 3rd control circuit on page74.

☞ Turn off the engine

➥ Do not turn off the ignition.

☞ Press tip switches 72 and 73 on the control lever between 5 – 8 seconds.

➥ Hydraulic lines are depressurized.

☞ Turn off the ignition and remove the ignition key.

Re-installingattachments

Re-installing attachments is described below for the standard bucket. If you are fitting or removing attachments with their own hydraulic functions (e.g. high-tilt or side dump bucket), you must follow the information provided in the Operator’s Manual of the attachment.

Fittingattachmentsontothequickhitchfacility

WARNING!

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