Page 8: Checking For Wear & Damage
CHECKING FOR WEAR AND DAMAGE Premature wear to internal parts is a result of either:- 1. Insufficient or incorrect lubrication. 2. The ingress of debris in the hammer. 3. Incorrect service and storage. The maximum wear allowance shown in this section are a guide as to when to replace parts. In certain conditions parts may need to be replaced before they reach the sizes shown. - Page 9 Pistons with wear patterns, or indentations deeper CHAMFER “B” than 2mm should be replaced.

Page 11: Rebuilding (Assembly) Of Hyper Hammers
REBUILDING HYPER HAMMERS 1. Ensure all the maintenance work outlined in the previous section has been completed. 2. Lay the wearsleeve on two wooden blocks, support the chuck end so as to raise the sleeve 50mm - Backhead 70mm off the ground this will make it easier to screw in the chuck assembly. -
Page 12: Lubrication
This is equally important that the lubricator system must be adjustable and have a visual check to ensure the lubricator does not run out of oil. As a good general guide, all Robit Hyper hammers require a third of a pint of oil per 100cfm of air through the hammer ( 0.07 litre per metre cubed) Eg Hyper 181 operating at 150psi = 2016cfm = 6.7 pints per hour... -
Page 13: Hammer Storage
The hammer should be stripped and cleaned and free of all water/moisture as possible. Robit T220 or similar rock drill oil should be poured into backhead (see chart below for quantity) allowing all parts to be coated throughout the hammer. - Page 14 0.300” - 7.62mm 0.740” - 18.80mm Chuck Release Washers are fitted to the Robit Range of Hyper Hammers to assist the removal of the Chuck from the Wearsleeve after drilling.

- Page 15 9.000” / 229mm HYPER 181 BACKHEAD There are many different “Splitting” Machines available for unscrewing the threaded connections on a Robit Hyper Hammer, some are attachments to the Drill Rig, others are independent hydraulic units, or purpose made Bench arrangements. Regardless of which machine is chosen they all require some method of securing the Wearsleeve whilst applying a torque to either the Chuck or Backhead.
