Caution: Do not drop clamps onto hard surfaces or strike with hard-faced objects as they may shatter. Note: Top clamps and suspension upright clamps are specific to left and right, and are not interchangeable. Note: Clamps will become more rigid and brittle in temperatures near or below zero. In warmer temperatures they will become more flexible. Note: In cold weather, the front knuckle clamp can be greased, along with D and E tube ends.
7.2. Clamp Operation Note: Clamps are fitted with security screws that engage holes in the tube ends. This gives extra safeguard against tube pull-out. This is particularly important on rough ground or when cart is being towed.
7.2.1. Assembly 1. Loosen security screws (if used) so that they are just clear of clamp bores. 2. Jack clamps apart with the clamping/jacking screw, just enough to insert or remove the tubes. 3. Line up tubes to match the angle of the clamp bore and slide into place. 4. To close clamp, tighten screws ¼ turn at a time, alternating from screw to screw, to finger tightness using socket tool provided. Caution: Do not overtighten. 5. Tubes should be clamped just enough not to move.
7.2.2. Dismantling 6. Loosen each clamp with ¼ turns anti-clockwise, working around all screws. Caution: Take care only to jack clamps apart sufficiently to release clamping pressure on tubes. Overjacking will damage clamps. 7. If security screws are used, loosen them sufficiently to clear holes before pulling the tubes out. Note: For rapid deployment next time the cart is used, the operator may choose to leave sections of the cart pre-assembled, e.g.: • data logger / battery bracket / H tube / I tube
Page 10 of 32
OM3228 iss 2
BARTINGTON INSTRUMENTS
• suspension springs / upright clamp / top clamp / tubes A, B and C • sensor bar clamps / tubes F and G See Section 9.1: Push/Pull Cart Assembly Overview for explanation of these parts.
7.3. Screws Overview Turn screws clockwise to grip tubes and prevent them becoming detached from their correct position. Turn screws anticlockwise to jack or spread the clamps, to allow tubes to be inserted or removed. Caution: Lightly tighten screws on clamps using only the socket tool provided. Caution: Do not overtighten screws or overjack clamps. Caution: Check screw tightness regularly during fieldwork, particularly where the cart is subjected to vibration. Caution: In push/pull configuration, security screws may be used at the operator’s discretion. Security screws should always be used in towing configuration. Note: Clamping/jacking screw heads and security screw heads should always face outwards from the cart. Note: When assembling the cart, the last operation is a final tightening of all clamping screws.

Caution: Your suspension has been rated for the number of sensors originally specified at time of order. If you wish to vary the number of sensors, contact Bartington Instruments for advice on whether you need to adjust the spring leaves. Caution: Always check the suspension for stress before and after operation of the cart. Stress is shown by delamination on the spring leaves. Replace if stress is evident. These checks are especially important if towing over rough terrain.
8.2. Suspension Assembly Instructions Springs come pre-assembled and consist of three types of leaf springs of different lengths, held together by clamping plates. Customers can dismantle and re-assemble them with leaf springs of different thickness. After replacing springs, reset the leaf springs by tightening the screws, washers and lock nuts to finger tightness. Note: The clamping plates must only apply friction, not a clamping force. Note: If towing, and/or if more than 6 sensors are utilised, suspension can be made harder by replacing the leaf springs with thicker leaves. This can be done incrementally by replacing individual layers. Contact Bartington Instruments for further information. Caution: Swing arms and springs must always trail the direction the cart is travelling. Hence their configuration depends on whether the cart is being pushed or pulled/towed. See Section 9.4: Wheel Assembly for details.

Close each clamp and tighten.
9.5.3. Positioning Sensors Step 13. Position sensors into clamps previously fastened to sensor bar. Caution: Do not overload the sensor bar. Note: When set up for manual pushing or pulling, the cart will be stable with up to four sensors fitted. WARNING: The balance of the cart will be altered when it is being loaded/unloaded with equipment. If sensors are loaded first, this will cause the front of the cart to spring up. Ballast should be attached to the front platform to compensate for this. Caution: Be sure always to load a suitable amount of weight towards the handle end to maintain a roughly neutral front to rear balance. Tighten clamps just enough so sensors do not rotate or slide. Note: The sensor bar and all sensors can be rotated 180° and moved in a linear direction, left or right. Caution: Rotate sensor bar only by manually turning tube. Do not use sensors as levers. See Section 11: Sensor Setup for sensor operation and attachment of accessories.

11. Sensor Setup 11.1. Setup with Bartington Grad-01-1000L Sensors and DL601 Data Logger Note: Contact
[email protected] for guidance on setting up the sensors in NMEA format. When using Bartington Instruments Grad-01-1000L sensors, the data logger should be set to NMEA mode. Data logging takes place using a laptop running third party software. Note: A separate data logger is required for each pair of sensors. Each data logger is powered by one BC601 standard battery cassette. Note: Some older data loggers are not able to support NMEA mode. These should be returned to Bartington Instruments for upgrading. Attach the data logger(s) to the data logger bracket [4]. Attach battery cassette(s) to the battery bracket [9b] and GPS system to the GPS clamp [9c]. Sensor setup follows the same procedures as for the standard Grad601 Single Axis Gradiometer System, described in the Grad601 Operation Manual (OM1800) available on the Bartington Instruments website. Caution: Do not use sensors as levers. Grip the sensor bar itself when rotating it. Note: You will need to locate a quiet magnetic spot in order to perform the adjustment. To simplify the process, pairs of sensors may be set up separately from the cart so as to avoid having to find a quiet magnetic area that is suitably large. A Grad601-2 carry beam from the Grad601 gradiometer system will be required for this. Note: Set-up for both Grad601 and Grad-13 sensors includes a stage of rotating the sensors by 180o. The sensor bar rotates so that this can be accomplished without detaching the sensors from the cart. Note: Connecting cables of different lengths may be supplied to accommodate the increased distance between sensors and data loggers. These should be fastened to the cart frame to prevent damage.
11.2. Setup with Third Party Sensors and/or Data Logger If using non-Bartington instrumentation, consult the manufacturer’s documentation. Bartington Instruments is unable to advise on the operation of third party products.
Page 29 of 32
OM3228 iss 2
BARTINGTON INSTRUMENTS
12. Cart Operation Once the cart and all required sensors are assembled as required, proceed over the area to be surveyed at a speed appropriate to terrain conditions. Caution: Not for towing on highways. Caution: Not to exceed speeds stated in the product brochure. Caution: Not for transporting any items other than scientific sensors and connected equipment.
13. Maintenance Keep all cart parts clean and free from grit. Keep all exposed threads clean, especially on the towing cart tube ends T1, T2 and T3. T1, T2 and T3 can be greased on assembly, to prevent binding. Note: Avoid use of grease in sandy / dusty conditions as this may cause a buildup of abrasive particles embedded in the grease.
14. Storage Clamps should be stored with the clamping/jacking screws in a neutral load (not under clamping or jacking pressure). Tubes can be stored horizontally or in an upright position.
15. Transportation Tubes should be strapped together for ease of handling. Clamps should be boxed and kept separate from other parts, to avoid damage. WARNING: Clamps can shatter if dropped.
16. Disposal This product should not be disposed of in domestic or municipal waste. For information about disposing of this product safely, check local regulations.
