Oil Shut-Off Valve; Multiplier With Pump Set - SaMASZ KW 141 Operator's Manual

OPERATOR'S MANUAL
Potential leaks shall be welded after the oil is drained. Drain plug (2) is located underneath the
tank (1). Damaged paintwork should be repainted and oil loss supplemented with HYDRAULIC
PREMIUM 46 HV oil group oil with similar properties. The tank holds approx. 150 l of oil – KOLIBER
400/450, 220 l of oil – CAMEL 900 and KWT 550/650/651. Refilling oil should be performed through
upper air vent filter (3). In order to perform this "can" should be dismounted from the tank, and only
special sieve shall remain inside, which collects impurities contained in oil. Oil level is indicated by
indicator plug, which should be unscrewed when oil is filled into the tank. Upon obtaining proper oil
level all plugs and filter should be tightened. Above the indicator plug there are hydraulic hoses nozzles
– tank fills (4).
The oil must conform with purity class: 15÷18 in conformity with ISO 4406, 9 in conformity with
standard NAS 1638. If the oil does not conform with the provided purity class then replace it. If the oil
purity is doubtful then it should undergo a purity test in corresponding testing authority.

6.5.2. Oil shut-off valve

Tightness of joint connections at valve (5) should be controlled at least once a day. Leaks should
be removed by tightening nuts and /or band clips (6) (Fig. 55).
Open position – lifting set along feeding hydraulic hoses (ON).
Close position – lifting set perpendicular to feeding hydraulic hoses (OFF).

6.5.3. Multiplier with pump set

Tightness of connections and oil level in multiplier should be examined as well as tightness of
connection of hoses to pumps (7) (Fig. 56). This activity should be performed at least once a week.
