Page 28: Protective Coatings
4500B USER HANDBOOK 3.3.3 Protective Coatings There are no special requirements for protective coatings on the hydraulic systems of a Toomey Scraper. The only consideration is to keep the steel hydraulic lines free from dirt and debris for extended periods of time as the moisture in the dirt and debris can promote accelerated corrosion of hydraulic lines. -

Page 39: Using The Scraper
4500B USER HANDBOOK 5 Using the Scraper 5.1 Coupling/Uncoupling Scraper Hitch The hitching and unhitching operations should be done on flat firm level ground in a well-lit place with no other vehicles or people around. It is important that anybody connecting or disconnecting the scraper is familiar with the tractor controls. -
Page 40: Loading
4500B USER HANDBOOK Reverse this procedure to uncouple the scraper from the tractor. Note that there may be residual pressure in the hydraulic circuits when uncoupling and to have an approved container handy to capture any hydraulic oil which may spill during this process. -
Page 41: Unloading
4500B USER HANDBOOK 5.3 Unloading The Toomey scraper incorporates a dual action ejection method. This is controlled hydraulically by a sequencing valve which means only a single operator control is required to control the ejection of material from the bowl. -
Page 42: Transporting The Scraper
4500B USER HANDBOOK 5.5 Transporting the Scraper If using a vehicle to transport the scraper first remove debris and material from the scraper. Make sure the scraper is empty. Check that the tie down points and lifting points are free from damage and all safety labels are present. -
Page 43: Maintenance Requirements
4500B USER HANDBOOK 6 Maintenance Requirements 6.1 Summary The ALG graders have been designed predominantly utilising grease free SKF bearings and bushes. This removes the requirement for regular greasing of the main pivots and cylinder clevises. Regular greasing is required for the Axle Hubs and Swivel Hitch. -
Page 44: Swivel Hitch
4500B USER HANDBOOK 6.2.2 Swivel Hitch If a TOOMEY swivel hitch has been supplied follow the instructions below. If an alternate brand hitch has been supplied, consult the maintenance documentation from that manufacturer. Pump grease into each of the three grease ports located on the left side of the hitch. Pump grease until grease starts to appear between the thrust washers either top of bottom. -
Page 45: Rocker Bearing Lock Nuts
If after 3 inspections the nut is still found to require tightening contact TOOMEY Earthmovers for advice. NOTE: Failing to check that the nut is sufficiently tight will result in the inner part of the bearing moving on the shaft and causing wear and damage. -
Page 46: Inspection Intervals
4500B USER HANDBOOK 6.4 Inspection Intervals 6.4.1 Main Pivot Inspections It is recommended that the main pivot pins (Drawbar, Centre Pivot & Swingarms) used with the PWM fiber wound bushes and wiper seals be removed for inspection every 1000 hours.
