## X. WORKING AROUND UTILITIES If it is suspected that utility lines such as, gas, water, phone or electrical power are in the work area, contact the local utility authority for line location BEFORE beginning work in the area. Use extreme caution around electrical power lines. Keep a sufficient distance away from electrical lines during operation. See chart below for minimum distances. <!-- image --> ## Y. SET LIMITS TO WORKING AREA Set limits around the working area to avoid collision, injury or death. Check for obstacles and personnel while swinging. Use a flagman to guide the operator whenever necessary. <!-- image --> ## Z. CAUTION FOR WORK IN URBAN AREAS It is dangerous to allow other personnel to enter into the working area. Make the working area off-limits to other people by providing barricades. Provide a flagman in working areas with heavy traffic to avoid accidents. ## AA. WORK WITH SUFFICIENT LIGHTING When working in dark places, turn on the work lamp. And if required, provide additional lighting facilities to assure good visibility. Stop working when it is impossible to ensure the visual field due to fog, snow or rain. ## BB. SLIPPERY OPERATION SURFACE Use caution when operating machine on boards or steel plates. Boards and steel plates become very slippery when wet. Pay special attention when working on inclined areas. Provide a device to prevent skidding and operate with extra care. Piled up tree leaves or branches also may causes skidding. ## CC. STRENGTHEN SOFT GROUND When working on a soft ground or marshy area, the machine may sink. Be aware that frozen ground becomes soft with the increase of ambient temperature. Use logs or lumber positioned in the opposite direction of the track to prevent the machine from sinking. １

## ［ 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 & 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 -->
