Operation

Pressure Relief Procedure

Trigger Lock

Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing or moving parts.

1.Engage trigger lock.

2.Shutoff the pump:

a.For air-powered pumps, close the bleed-type master air valve.

b.For hydraulic-powered pumps, close the supply line shutoff valve (U) first, then close the return line shutoff valve (V).

3.Disengage the trigger lock.

4.Hold a metal part of the gun firmly to a grounded metal pail. Trigger the gun to relieve pressure.

5.Engage the trigger lock.

6.Open all fluid drain valves in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to spray again.

7.If you suspect the spray tip or hose is clogged or that pressure has not been fully relieved after follow- ing the steps above, VERY SLOWLY loosen tip guard retaining nut or hose end coupling to relieve pressure gradually, then loosen completely. Clear hose or tip obstruction.

Always engage the trigger lock when you stop spraying to prevent the gun from being triggered accidentally by hand or if dropped or bumped.

Startup

1.Connect the suction kit (T) to the pump's fluid inlet, and place the tube into the fluid supply.

2.Prepare the pump’s power source:

a.For air-powered pumps, close the air regulator

(F). Open the pump's bleed-type master air valve (E).

b.For hydraulic-powered pumps, check the hydraulic fluid level before each use, and add fluid as necessary. Close the supply line shutoff valve (U) and the return line shutoff valve (V). Start the hydraulic power supply.

3.Hold a metal part of the gun (S) firmly to the side of

agrounded metal pail and hold the trigger open.

4.Start the pump:

a.For air-powered pumps, slowly open the air reg- ulator until the pump starts.

b.For hydraulic-powered pumps, open the return line shutoff valve (V) first, then slowly open the supply line shutoff valve (U).

1800 specifications

The Hitachi 1800 series excavators represent a significant leap in construction and earthmoving technology, designed to enhance productivity while ensuring operator comfort and environmental sustainability. These excavators are emblematic of Hitachi's commitment to advancing machinery engineering, equipped with an array of features and technologies that optimize performance.

One of the standout characteristics of the Hitachi 1800 is its powerful yet fuel-efficient engine. The machine is equipped with a Tier 4 compliant engine, which meets stringent emission regulations while delivering increased power output. This leads to enhanced digging performance and better fuel economy, reducing operational costs for excavating contractors.

The hydraulic system of the Hitachi 1800 is another remarkable feature. It utilizes a closed-center load sensing system that automatically adjusts hydraulic flow based on the load being handled. This technology allows for precise control during operations, whether digging, lifting, or swinging, and improves overall operational efficiency. The responsiveness of the hydraulic system aids in increasing the speed and accuracy of work cycles.

Operator comfort is prioritized in the Hitachi 1800 with its ergonomically designed cab. It offers excellent visibility, reduced noise levels, and adjustable seating, which enhance the operator's experience during prolonged use. Advanced climate control systems ensure that operators remain comfortable in various environmental conditions. The intuitive control layout, combined with a multi-function joystick, allows operators to manage all functions with minimal effort.

Additionally, the Hitachi 1800 incorporates advanced telematics technology, which allows operators and fleet managers to monitor machine performance in real-time. This technology aids in predictive maintenance, helping reduce downtime and extend the life of the excavator.

The excavator’s durability is another core characteristic. It features a robust undercarriage designed to withstand harsh operating environments, and high-strength materials are used across the machine to enhance longevity and reliability.

In summary, the Hitachi 1800 series excavators combine powerful engines, advanced hydraulic systems, and operator-centric designs to provide a robust and efficient solution for construction and earthmoving projects. With their state-of-the-art technology and commitment to sustainability, they represent an excellent investment for professionals looking to enhance productivity and performance on the job site.
