II. Using the Machine

Instruction Manual for an Electric-hydraulic Automatic Plastering Machine

This electric-hydraulic automatic plastering machine is ideal for plastering the vertical interior walls of residential, office, commercial, and other buildings. Please read this manual carefully to gain a working knowledge of the performance of the machine and learn how to operate it.

Before using the machine for the first time, the operator shall carefully learn its construction, the functions of its operating levers, and its operating procedure.

I. Preparations

1. Spray water on the wall surface as per relevant construction requirements so that it is sufficiently moistened.

2. Completely remove any protrusions on the wall surface, including small cement ones, to such a degree that the subsequent plastering may smoothly proceed.

3. The mortar to be applied shall be fully mixed with a mixer to achieve a uniform consistency, and shall be prepared according to the same formula that is used for manual plastering, except that it has a slightly lower water content than does the sort of mortar used in manual plastering.

4. Before using the machine every time, wipe the plastering blade with a rag soaked with machine oil to make it smooth, bearing in mind that both the upper and lower blade surfaces are to be properly processed.

5. Before the machine resumes running after a rather long interval during a job, be sure to splash water on the plastering blade.

II. Using the Machine

1. After the aforementioned preparations, switch on the power supply, and manipulate the phase-sequence converter lever (the central switch in the top row as shown in the sole close-up in the illustration below, marked with (9), which illustrates the operation panel) until the power indicator comes on. Place the machine on the plastering site and put it to an idle running test (which does not necessitate any manipulation of the hydraulic hoisting system). Start normal plastering after everything is found to be OK.

2. Push the machine close to the wall surface, hoist the crosspiece of the hoisting frame to 5cm~10cm below the roof, and adjust the verticality of the frame by means of the level.

3. Hoist the plastering blade to over 0.5m above the floor, select a relatively flat area of wall as a point of reference in selecting a plastering thickness, choose an appropriate feeler gauge according to the desired plastering thickness (the machine comes equipped with a set of feeler gauges ranging in thickness from 6 mm to 8 mm), adjust the plastering blade to an appropriate working angle, place the feeler gauge between the bottom of the plastering blade and the wall surface, push the machine until the feeler gauge is in as close contact as possible with the blade bottom, and hoist the hoisting frame until its crosspiece is propped firmly against the roof.

4. Withdraw the feeler gauge, lower the plastering blade to the lowest position, and add an appropriate amount of mortar to the machine.

5. Turn on the switch used for starting the vibration motor (the left button in the bottom row as shown in the close-up), and manipulate the lever used for hoisting and lowering the plastering blade (the left lever-type switch in the top row as shown in the close-up) without loosening your grip on it in the process (for otherwise the machine will stop). Now the plastering blade automatically starts to ascend along the wall, and upon reaching the greatest possible height, automatically turns and stops. Now press the button used for stopping the vibration motor (the right button in the bottom row as shown in the close-up) to stop the vibration motor.

6. Manipulate the plastering blade hoisting/lowering lever to lower the plastering blade to the lowest possible position, without loosening your grip on it in the process (for otherwise the machine will stop). The machine will stop automatically when it reaches that position.

7. Manipulate the lever in the illustration marked with (12) to restore the plastering blade to the plastering position. Manipulate the lever used for hoisting and lowering the hoisting frame (the right lever-type switch in the top row as shown in the close-up) to reduce and control the height of the frame as needed. Now move the machine to the next working position.

8. Repeat the aforementioned steps for the next plastering cycle (the machine plasters a 1 m-wide strip of wall each cycle, which lasts about 3 minutes).
