HYDRAULIC P.H.D. GENERAL INFORMATION The Hydraulic Post Hole Digger Operates differently to conventional three point linkage mounted diggers. The headstock frame that mounts to the tractor linkage LOCKS the three point linkage and therefore the DRAFT CONTROL must be DISENGAGED and NOT USED. Down pressure is obtained by the hydraulic cylinder acting on the jib frame

IMPORTANT BEFORE operating the Hydraulic Post Hole Digger PLEASE READ and be CONVERSANT with the SAFETY & OPERATING INSTRUCTIONS

FAILURE TO DO SO COULD RESULT IN

SERIOUS INJURY


HYDRAULIC P.H.D. ASSEMBLY GUIDE For ease of assembly it is suggested that all pins and shafts be lubricated. 1. Lower headstock stands to storage position and pin in place. Support headstock in

approximate vertical position and connect lower linkage arms to headstock frame in required hole settings with linkage pins, bushes. DISENGAGE DRAFT CONTROL

2. Fit top link bar and adjust so that headstock frame is approximately vertical or leaning

marginally towards the tractor, pin bar into position. Adjust and tighten linkage sway chains.

Raise headstock support stands and pin in transport position.

3. Fit hydraulic cylinder ‘body end’ to headstock frame. Connect hydraulic hoses to give desired lever movement of tractor control valve. Position and secure hydraulic hoses out of harms way. Fit jib frame to headstock frame and secure in position with pins. Extend hydraulic cylinder and connect ‘rod end’ to jib frame upper hole. Raise and lower jib to ensure full travel of hydraulic cylinder.

4. Check slip clutch attachment to the gearbox; ensure clamp bolts are torqued to

recommended settings. Lower jib to fit and secure gearbox into position with pin. Raise jib to maximum height and fit required recommended auger. Transport ground clearance to auger should be 300mm minimum. This will ensure a digging depth of approximately 1 meter. PLEASE NOTE..- Over digging will cause damage to the drive shaft safety covers and may result in the auger becoming locked in a buried position. To obtain 300mm transport clearance (auger tip to ground level) Increase/raise by adjusting headstock to lean towards the tractor and/or repositioning hydraulic cylinder to lower hole of jib. Decrease/lower by adjusting headstock to lean away from the tractor. These adjustments will vary depending on make and model of tractor being used.


5. Check length of driveshaft and adjust where necessary before fitting to gearbox and

tractor PTO. Ensure pins have located correctly in shaft grooves.

Fit and secure clutch cover and also drive shaft cover chains into position. 6. Lift jib, locate transport chain into storage position. Locate jib storage stands into

transport positions 7. Double check that all pins, nuts & bolts are fitted and secured and/or tightened correctly Read INFORMATION and SAFETY INSTRUCTIONS before commencing operations. CAUTION - IMPORTANT PLEASE FOLLOW “POINT 8” INSTRUCTIONS IF UNSURE CONTACT YOUR AUTHORISED DAKENAG DEALER

WARNING!

Avoid injury or death! Stay (3m) 10 FT away!

Read and understand the operator’s manual before operating or servicing auger.

Check for underground utility lines before digging.


SAFETY INSTRUCTIONS The Hydraulic Post Hole Digger operates with a very powerful rotation. The following Safety precautions MUST be followed at all times. STAND CLEAR Operator must ensure all persons stand at least 3 meters clear of equipment whilst in operation or raised position. BODY & CLOTHING Keep body and clothing clear of moving parts at all times. DO NOT OPERATE Until all parts and protective covers are in their secured operating positions. INSPECT BEFORE EACH USE Inspect the equipment for faults, wear & tear and damages. DO NOT ATTEMPT To remove any safety covers whilst the machine is in operation, whilst the PTO is engaged and/or whilst the tractor engine is running. Do not attempt to perform service and/or maintenance on the machine whilst the PTO is engaged and/or the tractor engine is running. Do not touch the auger, gearbox, clutch or driveshaft whilst the PTO. is engaged and/or the tractor engine is running. Do not attempt to use auger extensions with this product Passengers must not be on or near the digger when operating and do not attempt to leave the tractor seat when operating this machine ALWAYS Disengage the PTO, apply park brake, switch off engine and remove tractor key if tractor & machine is to be left unattended CAUTION: DURING OPERATION Limit down pressure to ensure tractor wheels, remain on ground Do not operate on excessive slopes If clutch slips, reduce down pressure and/or check hole for obstructions


OPERATING INSTRUCTIONS CAUTION! BEFORE operating check that the DRAFT CONTROL is DISENGAGED DRAFT CONTROL MUST NOT BE USED LIMIT DOWN PRESSURE TO ENSURE TRACTOR WHEELS REMAIN GROUNDED OPERATION PROCEDURE 1. Release auger transport chain and secure in store position. 2. Raise/lower jib by remote control valve on tractor. 3. Position auger over required hole site. 4. Lower jib to the auger tip contacts the ground surface 5. To achieve a vertical hole adjust the travel arc of the auger by moving the tractor

forwards/backwards as necessary. 6. Engage 540 rpm to run at a fast idle, operate auger in the 50 to 100 rpm range IMPORTANT Digging should be performed in depth increments of 300 - 500 mm at which time the jib should lifted to spin off soil and clear the hole. Soil type and condition will determine the frequency of the JIB LIFT AUGERS It is VITALLY IMPORTANT to use the augers specifically designed for this machine. This will ensure a smooth and efficient operation.


SERVICING & MAINTENANCE The Gearbox is pre-filled with Shell Alvania E.P (LF) 00 grease (or equivalent). The manufacturer states that this high quality oil has a working life of at lease 250 hours of operation. Providing no leaks are detected, no additional oil should be requited until the 250 hour service. All bearings in the gearbox are pre-lubricated for life. Where grease nipples are provided on the drive shaft, these should be lubricated regularly before use. Initial Service (prior to use): Ensure that all nuts, bolts and pins are fully tightened, inspect gearbox and drive shaft, and lubricate if necessary. 100 hour Service (after every 100 hrs of use): Repeat ‘initial service’ Check level of oil in gearbox Inspect drive shaft and auger for wear 250 hour service (after every 250 hrs of use): Repeat 100 hour service Replace gearbox oil with Shell Alvania EP (LF) 00. Grease or equivalent gear oil. Adjusting the clutch: Clutches are preset to manufacturer’s specifications. Daken recommends that inspection and maintenance of the post hole digger clutch be performed by your Local Authorised Dakenag Machinery Dealer.


AUGERS & CUTTING TEETH Augers range in size from 6” through to 18”, and are manufactured from heavy duty 5mm flighting, to suit H.F. Application and are standard clockwise direction.

Installation Instructions Quick Change teeth with rubber lock

1. Cut Ribd Rubr-Lok as long as the tooth is wide at the langs.

2. Insert evenly in holder. Note: Water may be used as a lubricant to install Ribd Rubr-Lok but NEVER use grease or oil.

3. Drive tooth fully in until seated in holder. Using Pengo.s SH-35 soft steel hammer. Compression of Ribd Rubr-Lok holds firmly in pocket. For tungsten carbide teeth: cushion carbides with softwood board before driving fully in.

4. Remove worn teeth with drift punch. Replace Ribd Rubr-Lok only if damaged

WARNING: Always wear eye protection when installing and removing teeth.

The Manufacturer recommends the use of the following grades of teeth and pilot bits: Standard: Ordinary digging in normal soil conditions, including some loose rock Hard Faced: Abrasive soil conditions, high impact, loose rock Tungsten/Carbide Tipped: Compacted rock. Abrasive soil, no impact.
