## ［ 1. SAFETY PRECAUTIONS ］ ## O. OPERATING ON INCLINES OR SLOPES - ・ Operation of this machine on an incline or slope may cause the machine to become unstable or unbalanced. Work up and down inclines or slopes, do not across. Do not swing or turn machine around on a slope. Build a level area for the machine to operate. Operate controls carefully to prevent sudden movements which may cause the machine to slide or rollover. - ・ When the engine was stalled, put down the bucket on the ground and return every lever to the neutral position, then start the engine again. - ・ Even if the swing operation is stopped on a slope, the machine might swing by the machine s own weight. ' - Operate the machine carefully when you operate the machine on a slope. - Place the bucket to the ground when you park the machine by necessity on a slope. ## P. FROZEN &amp; SNOW COVERED WORK SITES Use extreme caution when operating the machine on frozen or snow covered work sites. Operate all controls slowly and cautiously to prevent sudden movements such as start/stop/turn, that may cause the machine to unexpectedly shift, slide or move. Even on the slightest slope, when snow is present or work area is frozen can allow a machine to unexpectedly move. Snow on shoulders or snow drifts can be much deeper than expected. The machine can easily become buried under such conditions. Use extreme caution while operating the machine around or in snow. Be careful for frozen ground that becomes soft along with the increase of ambient temperature. ## Q. SWING / TRAVEL FUNCTION Make sure the swing and travel area of machine is clear of all persons and obstacles before operating swing/travel controls. Sound horn before operating swing/travel machine. If necessary, have a flagman signal operator during operation to prevent injury to persons or damage to obstacles and equipment. <!-- image --> <!-- image -->
