Page 28: Machine Preparation
Lifting Equipment Spearhead recommends that the cutterbar is stored on a substantial and suitable pallet in good condition when not in use. If it needs to be moved use a pallet lifter or forklift or sufficient capacity to cater for the weight of the cutterbar. -
Page 29: Post-Delivery/First Use Inspection
Spearhead machines are tested after manufacture. It is important to assess the machine to ensure that it is of the correct specification ordered from Spearhead or local Spearhead dealer. Information with regards to the specification of the machine can be found on the serial plate. -
Page 30: Usage Instruction
Section 2.9. The connecting tractor and reach arm will also have them as well with information given in the operator’s manual. If any part of the operation safe use of the machine is not completely understood, consult a local Spearhead dealer or Spearhead for complete explanation. -
Page 31: Controls Overview
Figure 4.3 The cutterbar can be mounted on Spearhead’s range of Twiga reach arms; Twiga Compact, Twiga Classic, Twiga Mid, Twiga Pro and Twiga Flex. In addition, it can also be mounted on Spearhead’s Twiga Carrier loader frame. Always bear in mind that the maximum oil flow that the cutterbar needs is also the flow that the loader frame or hydraulic reach arm is able to supply. -
Page 32: Machine Protection Guard
8999169EN: v1.0 25/01/2022 Depending on which reach arm/loader frame you wish to fit the cutterbar will determine how the cutterbar will be required to be fitted to the reach arm. Some models require an intermediate adaptor bracket to be fitted to the cutterbar to allow it to be successfully fitted to the reach arm and others have a simple, direct fitment. -
Page 33: Hydraulic Installation
8999169EN: v1.0 25/01/2022 The machine protection guard must be removed prior to start up with the motor switched off and the oil not under pressure, and replaced only once the machine has stopped completely – the guard should be in position at all times during transportation of the machine as a means of safeguarding people and machine. -
Page 34: Hydraulic Hose Checks
8999169EN: v1.0 25/01/2022 Disconnecting IMPORTANT: The machine should be secure at all times when left unattended so it doesn’t move. Ensure that the machine is stored off the ground, preferably in a dry location to preserve its condition; for example on a pallet. -
Page 35: Sharp Bends

Page 37: Bystanders
8999169EN: v1.0 25/01/2022 4.7.2 Bystanders It is of upmost importance that the tractor and reach arm and attachments are stopped immediately if a bystander comes within 90m (300 ft) while operating. The engine should be idled and the PTO disengaged. Do not restart work until the bystander is well past the 90m (300 ft) and the work zone has been reassessed to ensure there are no external risks. - Page 38 Refer to the operator manuals for the tractor and reach arm. Spearhead SP cutterbars can be supplied with different motors depending on the carrying reach arm in which they’re meant to be fitted to. See Table 4.1 For guidance on the correct oil flow requirement for the specification of cutterbar supplied.

Page 39: Starting The Cutterbar
8999169EN: v1.0 25/01/2022 4.8.2 Starting The Cutterbar Once pre-start checks have been carried out, the machine is can then be started. Start the machine at low oil flow (low rpm). If the machine is starting from cold, warm the machine up for approximately 15 minutes to heat up the oil. -
Page 40: Hedge Cutting Hints
All Spearhead cutterbars are designed to be operated at an angle in relation to the direction of travel. This ensures an optimal cut, as the branches often bend slightly in the direction of travel, and the newly cut branches easily “slip past”... -
Page 41: Transporting The Cutterbar
Angle the attachment in order to take up the least amount of space. For Spearhead machines with slewing ability the reach arm should be slewed behind the tractor. Be mindful, if the reach arm is lifted to the transportation stop that it doesn’t hit the cab of the vehicle or will hit the cab during transportation. - Page 42 It is of upmost importance that safety decals are kept clean and replaced if they are no longer legible, damaged or lost completely. Safety decals can be purchased readily from a local Spearhead dealer. After work and all debris is swept away from footpaths and highways ensure that the work site is tidied.
