• To reduce risk of fire, machines should be completely cleaned of debris at least daily, particularly around the engine exhaust components.
Hydraulic oil leaks, excess grease, fuel and oil accumulation (including spillage) should be eliminated immediately, always shut off engine before cleaning machine. • Maintain a clean cab interior, clear away trash or debris.
• Machine should be washed completely at every major service. • Inspect the machine daily for signs of damage or unusual wear, to structures. • Check for fluid leaks, or faulty operation. Repair or replace malfunctioning parts and systems immediately. • Check windows and door guards for damage. • Check protective windows for cracks, a damaged window has reduced strength to stop flying objects.
All damaged windows must be replaced with original equipment. • Check windows for scratching, crazing and cloudiness that could impair clear visibility all around the machine.
• Do not operate the machine with any defective or inoperable components. • Check all fluid levels.
• Do not operate the machine with any of the exhaust system, safety covers, oil shields, or other devices removed.
Safety
WORKING WITH OIL
Direct contact with oil implies a risk of skin complaints such as eczema. Strict hygiene should always be observed:
• Oils used in this machine may be hot enough to cause serious burns.
• Avoid contact with oil, particularly heated oil. • Oil on the skin should be washed off immediately with soap and water. • Wear protective gloves. Hands should be clean before putting on gloves. Apply protective cream to the hands to make washing easier. • Do not put oily rags in your pockets. • Oil soiled clothing should be changed as soon as possible. • Always keep an extra overall handy, but not in the machine where it can become dirty. • Cuts and abrasions must be attended to immediately. Clean them and apply first-aid. • Avoid breathing in oil fumes. • Wash hands and arms frequently. For example, at each meal break or as often as possible.
• Keep a first aid kit in an easily accessible location on the vehicle at all times.
Safety
SAFETY HAZARDS–VITON SEALS
O-rings and other seals manufactured of Viton material (fluorine rubber) produce a highly corrosive hydrofluoric acid when subjected to temperatures above 315°C (600°F). This contamination can have extreme consequences on human tissue since it is almost impossible to remove after contact.
The following procedures are recommended when inspecting equipment that has been subjected to high temperatures such as fire: • Visually inspect any seals or gaskets which have suffered from heat; they will appear black and sticky.
If these are found, DO NOT TOUCH!!! • Determine the material composition of any seals or gaskets, If fluoro-elastomer seals (Viton, fluorel, or tecmoflon) have been used, the affected area must be decontaminated before undertaking further work. Natural rubber and nitrile materials are not hazardous.
• Wear disposable heavy duty neoprene gloves and decontaminate the affected area by washing thoroughly with limewater (Calcium Hydroxide solution). • Safely discard any cloths, residue and gloves after use.
NOTE: Burning discarded items is not recommended except in an approved incineration process where the dangerous products are treated by alkaline scrubbing.
SAFETY HAZARDS–OPERATING
• Maintain a charged fire extinguisher on the vehicle at all times and KNOW HOW TO USE IT.
• Do not carry passengers either in the cab or anywhere else on the machine. The vehicle is provided and approved with seating for the operator only. • Do not allow anyone to operate the machine who may not be physically fit or who may be under the influence of alcohol or drugs. • When moving the machine, watch that enough clearance is available on both sides and above the machine or any of its attachments. Extra clearance may be required particularly where the ground is uneven.
• Approach with extreme caution any area where overhanging electrical power lines are present.
Serious injury or death by electrocution can result if the machine or any of its attachments are not kept a safe distance from these lines. • Maintain a distance of 3 m (10 ft) between the machine or boom and any power line carrying up to 50,000 volts or less plus 12 mm (1⁄2 in) for each addition 1,000 volts above the 50,000 volt level. • If State/Provincial, local or job site regulations require even greater safety distances than stated above, adhere strictly to these regulations for your own protection. • If the machine must be transported, make sure that it is adequately secured to the transporting vehicle. Refer to Vehicle Moving Instructions page in
SECTION 2.
• Stopping the engine immediately after it has been working under load can result in overheating and premature wear of the engine components.
Reduce engine speed to LOW IDLE and let run for approximately five minutes to allow gradual dissipation of heat and also to reduce turbo speed.
This will also prevent loss of coolant by after boil and possible hot spot damage to the engine.
• Be aware when performing service and maintenance tasks that surfaces and grab handles in and around the engine and cooling system may become very hot when the engine has been running. Contact with hot surfaces may cause injury. • Comply with the instructions in this manual and also the regulations for the operation of this machine as outlined by your company. • Read, understand and follow all general safety precautions specified by the attachment manufacturer.
