Preventative Maintenance - Sunex Tools 4998 Manual De Operation

PREVENTATIVE MAINTENANCE

This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the pump in a well protected area where it will not be exposed to inclement weather, corrosive vapors,
abrasive dust, or any other harmful elements. The pump must be cleaned of water, snow, sand, grit, oil, grease or other
foreign matter before using.
2. Keep components clean at all times. Use every precaution to guard against dirt entering the system.
3. Cover couplers with dust caps when not connected to the system. All coupler threads must be clean and lubricated regularly.
4. Leave hydraulic hoses in the carton until needed.
5. Store hoses away from direct sunlight, moisture or temperatures above 75º F (24º C) or below 50ºF (10º C).
6. Do not stack hoses. The weight of the pile may flatten hoses on the bottom. Hang the hoses.
7. Inspect hoses and connections daily. Replace damaged components as needed.
8. Over prolonged usage, hydraulic fluid will leak from the quick disconnect connections, reducing the original hydraulic fluid
level in the pump's reservoir. To fill the fluid level in the reservoir to the proper height, follow these steps:
a. Use only good quality hydraulic jack oil. Never use brake fluid, transmission fluid, motor oil, alcohol or glycerin. Use of
other than good quality hydraulic jack oil voids warranty.
b. Disconnect the hydraulic hose and air source from the pump.
c. With the pump in its normal position, remove the air vent screw (#81) by turning it in a counterclockwise direction until
removed from the pump.
d. Place a small funnel in the air vent screw (#81) opening and fill the pump's reservoir to within 1/4" of the opening.
e. Replace the air vent screw (#81) by turning it in a clockwise direction until tight. Then turn the air vent screw (#81) in a
counterclockwise direction two complete turns.
TROUBLESHOOTING
This unit is virtually trouble free. However if poor performance is noted, check the following:
1. Check to see the shop air supply is between 90 to 175 psig at no less than 7.8 cfm. The pressure should be checked at the
pump's connection to the shop's air line.
2. Check to see the pump's reservoir is filled to the required height. See step #8 in the PREVENTATIVE MAINTENANCE section of
this manual for complete information on proper fluid level and specified fluid.
3. Check to see the air vent screw (#81) on top of the pump is opened two full turns from its stop position by turning it in a
counterclockwise direction. Refer to step #5 of the SETUP section of this manual for full details.
4. Check to see that all hydraulic and air components in the SETUP section, including quick disconnect components, are properly
and fully connected.
