Q: My mini excavator brush cutter is making a loud squealing noise while in operation, is this normal?

A:  Mini excavator Brush Cutters should not emit a “loud” squealing noise during operation. It could potentially be that the flow cartridge settings are off or that the routine maintenance involving greasing the direct is not being conducted. Please call your Blue Diamond Attachments Product Support Rep for further guidance.

Q: My brush cutter starts “chattering” every time I lift or extend the boom of my excavator, is this normal?

A:  It is common for a brush cutter’s motor to “chatter” when an operator is extending or lifting the boom arm of their excavator. This is because the priority flow valve on the excavator is diverting hydraulic fluid away from the brush cutter and to the boom arm, enabling it to have enough power to move. Blue Diamond Attachments recommends placing the excavator boom arm in the area where the brush needs to be cut prior to turning on the brush cutter and turning it off when the excavator boom arm needs to be lifted or extended to another area needing clearing.

Q: What is the torque spec for the blade bolts on my Blue Diamond Brush Cutter and how do I achieve that?

A: 1440 ft-lbs is the torque spec for your cutters blade bolts and can be achieved by using a torque multiplier.

Q: How do I know if my Blue Diamond Attachment is still under warranty?

A: Call Blue Diamond Attachments Warranty department and one of our reps will be more than happy to help you out. Please have the model and the serial number of your attachment on-hand to ensure efficiency.

Q: What is this loud noise that occurs when I am turning off the brush cutter?

A: It is the Hydraulic braking system. The relief valves help slow the blade carrier down quickly so that the operator is not endangered when exiting the machine.

Q: Is there a difference in quality between the Light Duty, Heavy Duty, and Severe Duty Attachment product lines?

A: All Blue Diamond products are of high quality, the difference between the product lines is their workload capabilities.

Q: Is my Severe Duty Brush Cutter bidirectional?

A: The Severe Duty Brush Cutters are not bidirectional. You can get the Excavator Severe Duty Brush Cutters to spin in the opposite direction by switching the flow cartridges to their opposite sides. Do not adjust the setting of the cartridges. For the Skid Steer Severe Duty Brush Cutters, swapping the motor hoses to their opposite sides causes them to spin in the opposite directions. This will allow you to wear down the opposite sides of your blades without the loss of power.

Q: What kind of maintenance do I need to complete to keep my attachment functioning within specified operating ranges?

A: There are daily, weekly, and monthly maintenance tasks that all attachments are required to have. Please refer to your Blue Diamond Attachments Operators for those specified tasks.

Q: Why does my Blue Diamond Attachments Pick Up Broom Gutter Brush Kit only have one brush?

A: The Gutter Brush Kit is designed to work on the side of the street that the gutter is on. Although it is possible to have two gutter brush kits it is not recommended as you could push the third hydraulic motor over the pressure limit for the hydraulic circuit.

Q: Is my Blue Diamond Trencher able to turn while running in the ground?

A: Blue Diamond Trenchers are designed to travel in a straight line, turning them while running and in the ground is improper usage of the attachment and will void any warranty left on the attachment if the attachment breaks or is warped due to this.

Q: Should I back up or turn on my Blue Diamond Backhoe Attachment while the bucket is still engaged in the ground?

A: The Blue Diamond Backhoe attachment is designed to move when the boom is retracted all the way and the bucket is out of the ground. Moving in any direction while the bucket is still engaged in the ground will torque the frame or cylinder causing them to break. The warranty will be voided due to abuse caused by improper operation of the attachment.

Q: If a cylinder goes out on my Blue Diamond Attachment, and it is still under warranty, can it be repacked?

A: No, the warranty covers replacement cylinders, not repacking. The old cylinder must be returned through our RMA system. Contact your Blue Diamond Parts and Warranty Team for instructions.

Q: A fork has bent on my pallet fork attachment. Is this a defect?

A: No, pallet forks are built for lifting evenly distributed weight and carrying it level. Bending comes from prying or using the end of the fork instead of the full fork for lifting.

Q: If my motor stops working, and it is still under warranty, should I take it apart?

A: No, please call your BD Product Support Rep as dismantling your motor may void your warranty.

Q: Can I pry with my forklift attachment?

A: We recommend that you do not pry with the forklift attachment as this causes damages to both the frame mast and tines. This will not be covered under warranty as it is classified as improper usage of the equipment and operator abuse.

Q: Can I lift boulders with my forklift attachments?

A: We recommend that you do not lift boulders with the forklift attachment as this could cause damage to both the frame mast and tines. This will not be covered under warranty as it is classified as improper usage and operator abuse.

Q: How do I keep my Severe Duty Angle, HD Series 2 Angle, or Pickup Broom Drum from moving off of the bearing on the dead shaft side?

A: In photo 1 you can see the wall of the inner collar of the bearing is thicker than the other. In photo 2 you can see the outer collar is also thicker on one side than the other. When installing the broom drum, be sure to slide the square motor coupler completely into the motor drive flange. While making sure the motor coupler has stayed deep in the drive flange, clock the outer collar of the shaft bearing by inserting a punch into the recess provided in the collar (see photo 3). The collar should tighten to the shaft due to the cam effect. Now tighten the set screws in the collar of the bearing (see photo 4). The broom drum should not move from side to side using this procedure.

Q: My plate compactor has a looking glass, does this mean I have to add machine oil to it? If so, how much?

A: Your plate compactor has a separate reservoir for machine oil that needs to be filled independently of the host machine tank. The reservoir must be filled a little bit above the halfway line on the looking glass to ensure proper lubrication.

Q: Will your bolt-on edge fit my Brand X bucket?

A:  The bolt hole pattern for the Blue Diamond bolt-on edge is 6″ on center, starting between 3 and 3.5″ from the edge. The bolt size is a 5/8” plow bolt. Check your bucket and compare. For questions on a specific one, contact your Blue Diamond Product Support Team for the exact pattern on that one.

Q: Why can I not get my broom or six-way dozer blade to do two things at the same time, like sweep and change the angle or angle and tilt the blade?

A: In the normally open position the hydraulic pressure is directed to the attachment’s primary function. Pressing the control to change the angle of a broom or the tilt of a blade diverts the hydraulic pressure to the secondary function of the attachment. Both cannot function at the same time.

Q: Do you offer any discount on shipping or how much do I have to order to get free shipping?

A: We do not offer free or discounted shipping at this time. Since we see freight as a cost that we have little to no control over, we feel our money is best spent building the highest quality products, charging a fair price for them, and backing them up with incredible service. One thing that can help, though, is that if you are a dealer purchasing whole goods, having some spare parts shipped with that order can save you a lot on shipping. Please contact your Blue Diamond Product Support Rep to coordinate this.

Q: What if I get wire or other materials stuck in my brush cutter?

A:

1. Park the cutter on its blade carrier on blocks

2. Dismount the motor

3. You can now see 2 large nuts on the spindle. Take these and the washers off.

4. Connect your host machine to the cutter and lift the cutter frame up off the blade carrier.
