Do not overload the machine by installing additional counterweights.
Page 294: Avoid Overloading
OPERATING MACHINE Avoid Overloading WARNING:  Do not penetrate the bucket into piles of soil and/ or gravel at fast travel speed to avoid personal accidents.  Avoid excavating or scooping loads when the machine is articulated, which could possibly cause the machine to turn over.
Page 295: Excavation
OPERATING MACHINE Excavation Loading Accumulated Soil IMPORTANT: Avoid operating the machine with the front wheels raised off the ground. Machine traction force is reduced and excessive loads are applied to the undercarriage. M4GB-05-003 Scoop load while driving the machine forward as described below.
Page 296 OPERATING MACHINE Digging and Loading Level Ground IMPORTANT: While excavating with the bucket or fork, never apply excessive traction force to the tooth tips with the bucket or fork tilted more than 10°. Failure to do so may result in cracks or damage to the front attachment.
Page 297: Grading
OPERATING MACHINE Grading CAUTION: Turn the Ride Control Switch OFF when performing work with the front attachment in the float position. Performing work with the Ride Control Switch ON and the front attachment lever in the float position, ride M4GB-05-011 control is active and may allow the attachment to drop while the machine is driving.
Page 298: Loading
OPERATING MACHINE Loading IMPORTANT:  Always maintain a clean surface for machine operation. Cleaning of materials such as soil spilled on the driving surface will reduce wear and/or damage on tires.  When carrying loads in the bucket, pay attention to the travel road surface conditions.
Page 299 OPERATING MACHINE Load and Carrying Method WARNING:  Be sure to provide tire stopper (1) in front of the dumping port.  Before raising the lift arm, slightly tilt the bucket back and forth to stabilize the load in the bucket to avoid personal injury or damage to the machine due to falling of the load.
Page 300 OPERATING MACHINE Loader and Dump Truck Combination Method WARNING:  Always maintain a flat work site surface. Avoid rapid turns and/or sudden braking while raising the lift arm with the bucket loaded to prevent the machine from tipping over.  Do not penetrate the bucket into a loading face at fast travel speeds to avoid personal accidents.
Page 301: Dozing
OPERATING MACHINE Dozing IMPORTANT:  Never attempt to forcibly push piled material higher than the bucket capacity. Premature wear of the tires due to slipping and/or waste of fuel may result.  Do not perform dozing with the bucket dumped. Abnormal excessive stress will be applied on the front attachment.
Page 302: Removing Snow
OPERATING MACHINE Removing Snow CAUTION:  Remove snow in the same method as employed in general loading work. However, pay attention to slippage of tires and obstacles covered with snow.  Turn the Ride Control Switch OFF when performing work with the front attachment in the float position. Performing work with the Ride Control Switch ON and the front attachment lever in the float position, ride control is active and may allow the attachment...
