3.1 Operation
The owner and/or operator shall have an understanding of the product, its operating characteristics, and safety operating instructions before operating the PALD. Safety information shall be emphasized and understood. If the operator is not fluent in English, the product and safety instructions shall be read to and discussed with the operator in the operator’s native language by the purchaser? owner or his designee, making sure that the operator comprehends their contents.
3.2 Maintenance
The I’ALD shall be maintained in accordance with the product instructions.
3.3 Inspection
(a) Visual inspection shall be made before each use of the IAI.D by checking for abnormal conditions, such as cracked welds, leaks, and damaged, loose, or missing parts.
(b) Other inspections shall be made per product operating instructions.
(c) Each PAW shall be inspected immediately if the device is believed to have been subjected to an abnormal load or shock. It is recommended that this inspection be made by a manufacturer’s or supplier’s authorized repair facility.
(d) Owners and/or operators should be aware that repair of this equipment may require specialized knowledge and facilities. It is recommended that an annual inspection of the PALL) be made by a manufacturer’s or suppliers authorized repair facility and that any detective parts, decals. or safety labels or signs be replaced with manufacturer’s or supplier’s specified parts. A list of authorized repair facilities is available from the manufacturer or supplier.
3.4 Damaged Equipment
Any PAID that appears to be damaged in any way, is found to be worn, or operates abnormally SHALL BE
REMOVED FROM SERVICE UNTIL REI’AIRED. It is
recommended that necessary repairs be made by a man ufacturer’s or supplier’s authorized repair facility if repairs are permitted by the manufacturer or supplier.
2-4.1.1.5 Load-SustaIning Test. With the lift platform at its maximum height, the jack shall sustain the load and shall not lower mon’ than 0.125 in. (3.18 mm) in the first minute nor a total of 0.1875 in. (4.76 mm) in 10 mm.
2-4.1.2 Load-LImiting Device Test
(a) Hydraulic transmission jacks with a single-stage hydraulic cylinder equipped with internal load-limiting devices shall be pumped against a measured load with the lifting platform within 1.0 in. (25.4 mm) above its low height until the load-limiting device is activated, at which time the jack must have been supporting no less than 100% of its rated capacity and no more than 125% of its rated capacity.
(1’) Hydraulic transmission jacks with multiple-stage hydraulics equipped with internal load-limiting devices shall be pumped against a measured load with final stage extended 1.0 in. (25.4 mm) to 2.0 in. (51 mm) above its low height until the load-limiting device is activated, at which time the jack must have been supporting no less than 100% of its rated capacity and no more than 125% of its rated capacity.
(C) Hydraulic transmission jacks equipped with lift arms and internal load-limiting devices shall be pumped against a measured load with the lift arm in the horizontal position until the load-limiting device is activated, at which time the jack must have been supporting 100% of its rated capacity and no more than 125% of its rated capacity.
2-4.1.3 Proof Load Test. A proof load, as defined in para. 2-2.6, shall be applied centrally to the lifting platform of the jack. The load shall be lifted and sustamed throughout the Lifting range. For purposes of this test, any internal load limiting device may be deactivated.
