Safety Warnings

Show/hide table

At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

Show/hide table

Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak.

General Information

Illustration 3	g02376236
Typical Hydraulic Hose Machine

The 4C-3670, 4C-5054, and 4C-3680 Hydraulic Hose Presses can be used on 3/16 inch -3 through 2.0 inch -32 hose and couplings. The 9U-5792 and 4C-5052 Hydraulic Hose Presses can be used on many Caterpillar XT Hoses with crimped fittings.

For information on cutting hose, orienting couplings, skiving, hose insertion depths, and other hose assembly information, refer to Tool Operating Manual, NEHS0768, "General Information Hose Assembly".

Hose and Coupling Selection

For the correct size coupling for each hose diameter refer to Technical Data & Information, PECP5030, "Cat Hose and Couplings Reference Guide".

Cleaning Hoses

Hoses that are not clean can cause hydraulic system component damage. Foreign material inside the ends of the hose can cause grip failure and sudden release of the coupling from the hose. The use of a blade-type cutoff saw or a wire brush skiver can also leave foreign material inside the hose. Use a 130-6061 Hose Cleaner Gp or 156-0058 Hose Cleaner Gp for cleaning the hoses. For additional information, refer to Tool Operating Manual, NEHS0643, "Using the 233-7191 Hose Cleaner Gp , 233-7192 Hose Cleaner Gp , 233-7193 Hose Cleaner Gp , and 265-4959 Hose Cleaning Groups", Using the 130-6061 Hose Cleaner Gp or 156-0058 Hose Cleaner Gp .
