K88Q Op8f8tOr'S GOtrtJ3aftiTlBtit CÎ66f Of foose tjtiJet;tg. ,ttj not use machine to carry loose objects by weans other than attachments designed for such objects.
Do not cerry riders.
Observe and know the mechanics of altamate exit routes. For your personal protection, do not attempt to climb on at off machine while machine is in motion.
Be sure exposed personnel in the area oT operation are dear of the unit bafora moving the machine or its attachments. Sound horn. Obey flagman, safaty signals and signs.
When backing, always look to whera the machine is to be moved. Be alert to the position of exposed personnel. Do net operate if exposed personnel enter tha immediate work area.
Maintain a safe distance from other machines. Prgvide suflicient clearance for ground and visibility conditions. Yield ñght-of-way to loaded machines.
Maintain clear vision of all areas of travel or work. Keep cab windows clean and repaired.
When pulling or towing through a cable or chain, do not start suddenly at full throttle. Take up slack carefully. Guard against linking chains or cables. Inspect carefully for flaws before using. Do not pull through a kinked chain or cabla due to the abnormal high stresses arm possibility of failure of the kinked area. Always wear heavy gloves when handling chain or cable.
Ba sure cables are anchored securely and the anchor point is strong enough to handle the expected load. Keep exposed personnel clear of anchor point and cable or chain. Do not pull or tow unleca operators compartments of machines Invoked are guarded against potential csble or chain backlash.
Be alert to soft ground conditions close to newly constructed walls. The fill material and waight of machine may cause the wall to collapse under the machine. in darkness, check area oJ operation carefully bafore moving in with machine. Use all lights provided. Do not move into areas of restricted visibility.
If engine has a tendency to stall for any reason under load or idle, rapoft thi6 for adjustment to a proper maintenance authority immediately. Do not continue to operate machine umil condition haebeen corrected.
Be sure to periodically check all engine exhaust parts for leaks as exhaust gases are dangerous to the operator. M operator must know the machine's capabilities. When working on slopes or near dropofis be alert and avoid loose or soft conditions that could cause sudden tipping or loss of control.
Where noisa exposure exceeds 80 dBA for 8 hours, wear authorized ear protective equioment per local and other nationa( safety requirements tnat apply.
Do not operate machinery in a condition of extreme fatigue or illness. Ba especially careful towards he end of the shift.
When demountable counterweights have baen provided, do not work machine if they have been removed. When operating machine know what clearances will be encountered: overhead doors, wiras, pipes, aisles, road-
ways: also weight limitation of ground, floors, and ramps. Be aware of fog, smoke or dust elements that obscure visibility.
Always check work area for dangerous features. The foliowing are examples of dangerous work areas: slopes, overhangs, timber, demolitions, fire, high wails, dropoffs, baclcfills, rough terrain, ditches, excavations, traffic, parking IoIs, crowded maintananca and closed areas. Use extrerr/b care when in areas such these.
Avoid going over obstacles such as rough ierrain, rocks, I0gs, curbs, ditches, ridges and railroad tracks whenever possible. When obstructions must be crossed, do so with extreme care and perpandicularty. Reduce speed. Ease up to the breakover point - pass the balance point slowly on the obstruction and ease down on the other side, using attachment as an aid if necessary.
Cross gullies or ditches at an angle (possibly using attachment as an aid) with reduced speed altar insuring ground conditions will permit a safe traverse.
The grade of slope you should attempt will be limited by such factors as condition of the ground, load being handled, the type of machine, speed Of machine and visibility. There is no substitute for good judgement when working on slopes.
Avoid operating equipment too ctose to an overhang or highwall either above or below the machine. Be on the lookout for caving edges, falling objects and slides. Beware of concealment by brush and undergrowth of these dangers.
Avoid brushpiles, logs or rocM. Do not drive the machine onto bruahpilee, toga, large rocks or other SurlaCe irregularities that break traction with the ground especially when on slopes or near drcpofls.
Be alert to avoid changes in traction conditon that could cau9e loss of control. Work the machine with extreme caution on ice or frozen ground conditions, on steep slopes or near dropofts.
Operating in virgin rough terrain that includes previously mentioned hazards is called pioneering. Be sure you know how this is done. Danger from falling branches and uptuming roots is acute in these areas.
Place the machine in relationship bet 'een the excavation and tha oump grea to swing to the left for discharge of material, for best visibility. Never use tha bucket or attachment ae a man I«t «• our iders on the machine.
No machine should ever be used as a work platform or scafiolding. Other uses that depart from machine design imended purposes (such as pushing or towing rail wagons, trucks or other machines) should be avoided.
Af¥yays be d‹vare Of preSeNCe Of peO#t/e”Irt the W0rk rite. Never swing Or position bucket, load or attachment over ground crew or truck cab.
Before loading a truck be sure the drivar is in a safe place.
Load trucks from the rear or side.
Use recommended buckets for machine, taking into ac cotJnt weigh! of material, loadability and heaping charac teristics of material, terrain and other pertinent job factors. Transport a loaded bucket with the buckat as far tipped back and in as low a position as possible for maximum visibility, stability and saiety transport of the machine. Carry it at a proper speed for the load and ground conditions.
Handle only loads which are safaly arranged. Beware of overhanging material or objects.
0o not swing k›ads over exposed peapte. Avo\d swinging loads towards the downhill side of slopes as this raduces the stability of the machine. Dump on the uphill side if at all possible.
Items to be lifted by the machine should be slung only from the designated lih point.
Excavators ara not designed for lifting and transporting loads and therefore should not be used for accurate positioning of materials; shou)d such service be occasionally required .(Iifting/lorating building materials) special precautions must be taken such as:
Anchorage of loads by suitable wire ropes or chains arid slinging hardware.
In no case whatsoever must any person be allowed to stand under swinging loads or even within maneuvering arab
Never exceed the load chart rating. FailMre of the bucket linkage or slings could result if chains or slings are incorrectly attached, resulting in death or personal injury.
Always ba sure that slings ueea to lift the load are of adequate strength for the purpose iNended, and that they are in good condition.
All ioaa ratings only apply to levai machine condition and muet be not ueed when worklng on slopea.
Avoid sidehill travel. Drive ug and down the slope. Should the machine start slipping sideways on a grade dig the buckat with teeth into the ground.
Operating on elopas is dangerous. Level off the working area if possible. Slow down the work cycle whera leveling cannot be acoomplishad.
Avoid swinging lull bucket or load in a downhill direction as this reduces tha stability of me machine.
Avoid working with the bucket on the uphill side. The counterweights, when su/ung downhill will am to reduce stability on slopes making tipping a dangerous possibility.
On grades work with bucket downhill after having first checked machine stability with empty bucket, booms retracted and swinging superstructure slowly through 360”, Position undercarriage perpendicular to slopes, overhangs, etc. to facilitate transport exit fiom area.
Remember that when the sprockets are located in front of machine and operator thg direction of travel will be inverted.
