VALVE GP-RELIEF 2603022 - Caterpillar

Failure to properly service the batteries may cause personal injury.Prevent sparks near the batteries. They could cause vapors to explode. Do not allow the jump start cable ends to contact each other or the machine.Do not smoke when checking battery electrolyte levels.Electrolyte is an acid and can cause personal injury if it contacts skin or eyes.Always wear eye protection when starting a machine with jump start cables.Improper jump start procedures can cause an explosion resulting in personal injury.Always connect the battery positive (+) to battery positive (+) and the battery negative (−) to battery negative (−).Jump start only with an energy source with the same voltage as the stalled machine.Turn off all lights and accessories on the stalled machine. Otherwise, they will operate when the energy source is connected.
To prevent damage to engine bearings and to electrical circuits when you jump-start a machine, do not allow the stalled machine to touch the machine that is used as the electrical source.Turn on (close) the battery disconnect switch prior to the boost connection to prevent damage to electrical components on the stalled machine.Use only equal voltage for starting. Check the battery and starter voltage rating of your machine. Use only the same voltage for jump starting. Use of a welder or higher voltage will damage the electrical system.Severely discharged maintenance free batteries do not fully recharge from the alternator after jump starting. The batteries must be charged to proper voltage with a battery charger. Many batteries thought to be unusable are still rechargeable.Refer to Special Instruction, SEHS7633, "Battery Test Procedure" for complete testing and charging information. This publication is available from your Cat dealer.
When the auxiliary start receptacles are not available, use the following procedure.
Lower the equipment to the ground. Move all controls to the HOLD position. Move the hydraulic lockout control to the LOCKED position.
Turn the start switch on the stalled machine to the OFF position. Turn off all accessories.
Turn the battery disconnect switch on the stalled machine to the ON position.
Move the machine that is being used as an electrical source near the stalled machine so that the jump-start cables reach the stalled machine. Do not allow the machines to contact each other.
Stop the engine of the machine that is being used as an electrical source. If you are using an auxiliary power source, turn off the charging system.

(1) Red positive post to starter
(2) The black negative post connects to the battery disconnect switch.
(3) Do not use these two connections for jump starting. The red positive post is connected in series to the black negative post.
(4) Cover
Ensure that battery caps on both machines are tight and correctly placed. Ensure that batteries in the stalled machine are not frozen. Make sure that the batteries have enough electrolyte.Note: The positive terminal of the 24 V
