AIR PUMP 300 BAR INSTRUCTION MANUAL

HOW TO ASSEMBLE

Follow these steps for assembling the air pump:

1. Attach the hose to the bottom of the pump.
2. Install the high-pressure hose using the provided wrench.
3. Attach the handle and connect the piston.
4. Test before using.

Visual guide shows connecting the hose, installing the high-pressure hose with a wrench, attaching the handle, and connecting the piston.

TROUBLE SHOOTING

Q: The gauge is not in right position or do not rise while pump working.

A: Check the gauge if damaged during delivery; it may need replacement.

Q: Hard to pull or falling off while pumping.

A: Change the small O-ring in the piston (parts #15/17).

Q: Automatically rebound during the down stroke.

A: Clean the air discharging valve (part #31) or the O-ring of the valve body (part #25).

Q: Pressure rising very slowly.

A: Check the following parts for leaks: 1. Handle, 2. Filter, 3. Female connector, 4. Hose, 5. Air bleed screw, 6. Gauge.

USE OF THE PUMP

1. Do not pump in a fast way; the maximum frequency is 50 times per minute.
2. This hand pump creates very high pressure; do not close the air outlet when it is working.
3. Pressure should not exceed the recommended pressure of 4500 psi.
4. Pump slowly and deliberately. Stop at the top and bottom of each stroke (1-2 seconds) to let the air flow through the tiny holes inside the pump.
5. Do not fail to go all the way to the end of each stroke; make each upstroke count, as most of the work is accomplished in the last 2-3 cm of pump rod travel.

WARNINGS AND MAINTENANCE

1. Do not pump for more than 5 minutes; leave the pump for 15 minutes for cooling after each pumping period.
2. Open the pump bleed screw to relieve the pressure in the hose; keep the pump in the pressure-free state when not in use.
3. Keep the pump in a dry and clean way; store the pump indoors away from extreme temperatures.
4. The new pump needs refueling after 800 times strokes. Drop 3 drops on the top handle and apply a few drops on the secondary tube. See Figure 1A and 1B.

Figure 1A and 1B show where to apply lubricant to the handle and secondary tube for maintenance.

OPTIONAL FUNCTION

1: Large size filter ?️

Illustrates a large filter component for the pump.

2: Extra couple of quick disconnector ?

Shows an additional quick-connect fitting for the hose.

3: Build-in moisture trap in handle ?

Depicts the pump handle with an integrated moisture trap, including a filter, female connector, hose, air bleed screw, and gauge.

Component Diagram

The following is a textual description of the exploded view diagram, detailing the pump's components:

• 1. Handle: The main grip for operating the pump.
• 2. Filter: Likely part of the moisture trap system.
• 3. Female connector: Connects to other fittings.
• 4. Hose: The primary flexible tube for air delivery.
• 5. Air bleed screw: Used to release pressure from the pump.
• 6. Gauge: Displays the current pressure reading.

The diagram also shows numerous internal components identified by numbers (e.g., 11, 14, 15, 17, 19, 20, 21, 22, 23, 24, 25, 26, 28, 29, 30, 31, 33, 34, 35, 39, 40, 41, 42, 43, 45, 46, 47, 48). These include parts such as piston assemblies, various seals (like O-rings for the piston and valve body), springs, retaining rings, and sections of the pump cylinder. These components work together to create the pumping action and pressure regulation.
