If the wire braid can be seen from the outside, it is time to replace the hose. Rubber hoses have a 2:1 safety factor. Thermoplastic hoses are frequently used with power-driven hydraulic pumps. Only 700 series thermoplastic hoses have a 4:1 safety factor. Use the following infromation to avoid problems with hoses: • Do not kink or tightly bend hoses. This will damage the wire braid. The minimum bend radius is approximately 4.5 inches [12 cm]. This means there should be no less than 9 inches [24 cm] between the straight sections of the hose as pictured. • The most sensitive part of the hose is at the fitting. To reduce damage, do not bend the hose at the fitting. Keep the strain relief (spring or boot) guard over the fitting as shown. It will help to support the hose. • Make the layout of the hoses such that there is no risk of damage due to vehicles, trucks etc. Do not drop objects onto hose. • Hoses are not designed to be used as a tow rope for your pump. Do not pull on the hose to move the pump. • Never pressurize a hose which has a kink or sharp bend. • Hydraulic pressure in a hose, cylinder or other component can increase due to heat. Never try to push check balls or pins in couplers to reduce the pressure. To avoid such problems, never store components in warm areas. REMEMBER: Always discard damaged hoses to eliminate the risk of someone else using the hose. The next user might not notice the damage until the hose is pressurized. A leak in a hose can cause high pressure oil to penetrate your skin. IF YOU ARE EVER INJURED BY A SPRAY OF OIL, SEE A DOCTOR IMMEDIATELY.
