General Precautions

Precautions on Operating Attachments

WARNING

Long attachments reduce machine stability. When traveling down steep slopes or

slewing on slopes, the machine may loose its balance and tip over.

The following operations are particularly dangerous. Do not perform them.

¡ Traveling down slopes

¡ Traveling across slopes

¡ Slewing on slopes

with the attachment lifted

OE3A2531

OE3A271

OE3A331

¡ When heavy attachments are installed, the overslew (the distance from where the

operation to stop slewing is performed until slewing stops completely) increases

and mistakes in judgment may result in the attachment hitting surrounding objects.

Allow for plenty of room between the attachment and obstacles.

In addition, the natural drop (the gradual dropping of the attachment under its own

weight when it is stopped in midair) also increases when heavy attachments are

installed.

¡ The machine can tip over more easily in the lateral direction than in the longitudinal

direction.

• Do not slew (swing) sideways with excessive weight at the front. In particular do

not slew sideways on slopes.

• The front is heavier for machines equipped with breakers, crushers than for

machines equipped with the standard bucket. Do not operate such machines

sideways, especially with the digging arm (boom) downhill.

¡ When a long arm or a telescopic arm is installed, the operating range suddenly

increases and mistakes in judgment may result in the attachment hitting surrounding

objects. Allow for plenty of room between the attachment and obstacles.

The digging capacity increases when the

bucket’s link arm installation position is

switched from (A) to (B). However, this

shortens the bucket stroke.

• Struck capacity (SAE) :

0.210 m³ (0.275 cu. yd.)

• Rated capacity (SAE) :

0.261 m³ (0.341 cu. yd.)
