NFORMATION Your Postmaster has been individually built with great emphasis on quality, strength and simplicity of design and with routine care will give many years of trouble free operation. The following instructions have been written to cover the use and maintenance of the machine. Care should be taken to ensure that you are referring to the correct section of your machine before carrying out any adjustments, or when ordering spare parts.
Daily Check Items 1. Check the unit is properly and securely attached to the crane/excavator unit. 2. Checks that all nuts and bolts are secure, mounting pins are properly retained, and all safety shields are in place. (All nuts and bolts should be checked after the first 10 hours of operation.) 3.

Round Section Contact Autoguide w/ fingers for post handling Specifying the Unit The 4 bolt mounting plate allows the fitment of brackets to suit most diggers in the quoted range. It is essential to confirm the pin diameter (D), pin pitch (C), and width of boom (W) before ordering.
OSTMASTER NSTALLATION The safe operation of this equipment is the responsibility of the operator, who should be familiar with the lifting process, the power unit and all safety practices before starting operations. Attaching the Postmaster to the Power Unit 1. SWITCH OFF the power unit. 2.
NSTALLATION Hydraulics Operation Operating the hydraulics one way causes the clamp to close, followed by the start of vibration. Reversing the flow opens the jaws without vibration. DO NOT run the machine without a post in the jaws. The Postmaster jaws have multiple positions that enable a wide variety of posts to be inserted without the need for special designs.
Jaw Spacing Below is the suggested pin arrangement for a range of post sizes and shapes. Certain posts will fit with a number of arrangements. When using the postmaster, an arrangement should be found that keeps the post as central as possible to the postmaster base.
Operation Sequence 1. Stand a post vertically, and move the Postmaster into position directly above it. 2. Keeping the post central in the jaws, lower the Postmaster until the base of the Postmaster sits on top of the post. 3. Gently operate the hydraulic circuit to close the jaws.
5. Using the boom, move the post into the desired position and push it into the surface if suitable ground. 6. Start the vibration and push the post into the ground, ensuring the post is pushed vertically downwards. 7. Once the post is installed to the desired depth, simply operate the Postmaster in reverse to release the jaws and lift the Postmaster away.
AINTENANCE 1. Keep all hardware tight – re-torque regularly until stable. 2. Inspect all hoses for signs of wear and replace as necessary. 3. Inspect the rubber buffers for signs of cracking – replace promptly to prevent failure. 4. The gearbox contains 1 litre of universal oil. This is sufficient for 12 months operation, so annually remove the lid, pour out the old oil, check all hardware, and add 1 litre of new oil.
It may be appropriate to wear radio communication equipment in conjunction with appropriate PPE, to ensure consistent safe communication. 3. We believe that when correctly operated, the Autoguide Postmster is safer than a conventional falling weight post driver. Nevertheless, take care to avoid contact with the machine and stay out of its working area whenever it is working.
